Introduction
The City Rail Link (CRL) project comprises the construction, operation and maintenance of a 3.4 km underground passenger railway, running between Britomart Station and the North Auckland Rail Line (NAL) in the vicinity of Mt Eden Station. The CRL involves the construction of two new underground stations at Aotea and Karangahape, and a redeveloped station at Mt Eden (refer to Figure 1-1). The design and construction of the CRL infrastructure between Aotea and Mt Eden Stations is being delivered by the Link Alliance. This Historic Character Delivery Work Plan (Archaeology Section) (HC DWP (Archaeology Section)) has been prepared in relation to the Mt Eden Enabling Works (“the Project”).
Figure 1--1: CRL Route and Location
1.1 Overview of CRL works in Mt Eden The CRL works in the Mt Eden area involve the construction of the southern section of the tunnel structures and the tie-in to the existing NAL, including the construction of the redeveloped Mt Eden Station. The Mt Eden Active Construction Zone (ACZ) and Construction Support Area (CSA) is generally located between Nikau Street to the north, State Highway 1 (SH1) to the east, Dominion Road to the west and the existing NAL to the south. The works in this area include: • • • • • Page 5
Construction of an underground grade separation structure near Mt Eden Station; A new Mt Eden Station building incorporating passenger linkages; Modifications to the existing Mt Eden Station platforms; Road over rail bridges at Mt Eden Road, Normanby Road and Ruru Street with sections of road realignment; Grade separation structures for the existing and new rail lines to pass-over and connect with each other;
| Mt Eden Enabling Works
Historic Character Delivery Work Plan (Archaeology Section) • •
Pedestrian and cyclist bridge structures at Fenton Street and Porters Avenue; and New road linkages within the reinstated area post-construction.
Given the nature and scale of CRL works in Mt Eden, construction will be undertaken in a staged manner. This HC DWP (Archaeology Section) only relates to the first stage of these works, the Mt Eden Enabling Works, as described in Section 2 below. Following completion of the Mt Eden Enabling Works, works in this area will involve: •
•
Main construction works – these works will include: Tunnel Boring Machine (TBM) operations, structure construction and waterproofing/tanking for cut and cover tunnels, utilities installation, retaining wall for Ruru street extension, construction of the rail line tieins including junctions and grade separation structures, realignment of the existing Western Line including platform reconstruction, grade separation of Normanby Road, pedestrian / cyclist bridges at Fenton and Porters, construction of the new station buildings. The Main Works will be undertaken from Mid 2020 through to 2024. Public realm reinstatement – these works will involve establishing the final finishings and features that will comprise the completed Mt Eden Station and surrounds and will likely to be undertaken from 2021 to first quarter-2024.
1.2 Purpose of the Historic Character Delivery Work Plan (Archaeology Section) This HC DWP (Archaeology Section) has been prepared to identify measures that will be implemented to mitigate and manage potential adverse effects on archaeology during the Mt Eden Enabling Works. The objective of the HC DWP (Archaeology Section) is: •
To avoid, remedy or mitigate adverse effects on archaeological remains during construction, as far as is reasonably practicable.
This HC DWP (Archaeology Section) addresses the requirements of CRL designation conditions 41.1 and 42 and will be implemented throughout the construction period. This HC DWP (Archaeology Section) has been prepared by Clough & Associates Ltd for the Link Alliance and forms part of the Construction Environmental Management Plan (CEMP) for the Project. It has been prepared in consultation with the Mt Eden Community and Business Liaison Group (CLG) and reviewed by Independent Peer Review (IPR) prior to submission to Auckland Council (as per designation conditions 7 and 11).

Project Description
In order to launch the TBM and commence construction of the CRL tie-ins to the NAL, a range of ‘enabling’ works are proposed, which are the subject of this HC DWP (Archaeology Section). These enabling works are described in detail in the CEMP. In summary, the Mt Eden Enabling Works involve: • • •
•
• • • •
Continuation of the demolition and clearance of the Mt Eden CSA (these works are authorised under the Mt Eden Demolitions Outline Plan). Set up of a temporary site office, which is anticipated to be a 2-3 storey modular building (likely made up of containers) located in the western extent of the CSA. Piling and excavation associated with the preparation of the portal. This will involve the demolition of the redundant stormwater shaft located in the portal area; the installation of bored piles and associated works (ground anchors and shotcrete) to support the excavation face; and removal of spoil. Bulk excavation to form what will become the rail trenches/cut and cover tunnels, which will also provide a ramp for the TBM to be manoeuvred into position. The excavation will encounter basalt, which is to be blasted in order to expedite the works and minimise the amount of rock-breaking required. In places, softer ground conditions are anticipated to be encountered, which may require the use of sheet piles. Local mined tunnelling to facilitate the TBM launch. Construction of the additional Mt Eden Road bridge (north of the existing bridge), including temporary diversion of shallow utilities in this location. Construction of the Ruru Street bridge, including diversion of the Huia 2 watermain in this location. Temporary and permanent utility diversions (such as water, wastewater, stormwater, Vector overhead cables and ducting, gas and communications) along Fenton Street, Porters Avenue, Haultain Street and Wynyard Street to provide adequate clearance between the Huia 2 watermain and NAL, associated retaining walls, and the proposed Fenton Street pedestrian bridge.
2.1 Construction methodology The Project will be divided into stages as described in the CEMP.
2.2 Site description The Mt Eden Enabling Works are being undertaken in the vicinity of the existing Mt Eden Station, which is an existing urban environment. The Project area is generally bounded by the NAL (south), Ngahura Street (west), Mt Eden Road (east) and Nikau Street (north), and is bisected by Shaddock Street. The enabling works will also include works along Mt Eden Road, Fenton Street, Porters Avenue, Haultain Street and Wynyard Street.

Historic Character Values – Archaeology 3.1 Archaeological Sites in the Mt Eden Enabling Works area
Three archaeological sites have been recorded within the Mt Eden Enabling Works area. These are: 1. R11/51, a shell midden site related to Māori settlement, recorded in the 1960s near the railway lines and within 31 Ruru Street, but subsequently destroyed by development works. 2. R11/3079, a pre-1900 building and any associated subsurface remains at 31 Shaddock Street. The building will have been demolished prior to the enabling works following detailed archaeological investigation and recording, which has been provided for under a separate DWP. However, there is potential for associated subsurface remains to remain in situ on the property. 3. R11/3080, a pre-1900 building and any associated subsurface remains at 6 Flower Street. The building will have been removed prior to the enabling works following detailed archaeological investigation and recording, which has been provided for under a separate DWP. However, there is potential for associated subsurface remains to remain in situ on the property. The archaeological requirements relating to the two pre-1900 buildings (R11/3079 and R11/3080) were addressed in the Mt Eden Demolition Historic Character Delivery Work Plan (Archaeology Section) 2018. The Mt Eden Enabling Works have the potential to affect archaeological remains relating to two of these three recorded sites (R11/3079 and R11/3080). In addition, 19 Shaddock Street, is the location of a 1920s timber building, and has been identified as having some potential for subsurface archaeological remains relating to earlier (pre-1900) occupation of the property. Modern development within properties elsewhere in the Mt Eden Enabling Works area and within road reserves will have removed most evidence of pre-1900 European or earlier Māori occupation. However, it is possible that parts of deeper features such as wells may survive partially intact and the presence of remnant Māori occupation remains cannot be excluded. The possibility that subsurface pre-1900 or early 20th century archaeological remains may be exposed during the Project will be mitigated and managed through the implementation of this HC DWP (Archaeology Section) and an Archaeological Authority (no. 2017/793) issued by Heritage New Zealand Pouhere Taonga (HNZPT) for the wider CRL project (“the HNZPT Authority”) (see Appendix A).

Roles and Responsibilities 4.1 Project Archaeologist Roles and Responsibilities
The Project Archaeologist (refer Table 4-1 below) will be responsible for ensuring that the archaeological requirements set out in this HC DWP (Archaeology Section) and in the HNZPT Authority are fulfilled. This includes ensuring that the Project Archaeologist (or other qualified archaeologist under their direction) is available to monitor earthworks where required and respond to call-in by the construction contractor if any suspected archaeological remains are exposed. It also includes ensuring that the archaeological team adheres to the contractor’s site safety requirements and that a Site-Specific Safety Plan for the enabling and main works at Mt Eden Station is prepared. The Project Archaeologist will also be responsible for reporting to the relevant parties regarding the archaeological work.
4.2 Link Alliance/Contractors Prior to the start of the Mt Eden Enabling Works, the Link Alliance/contractors will arrange an onsite meeting with the Project Archaeologist and Mana Whenua representatives, who will provide a briefing on archaeological and cultural requirements for the works. The Project Archaeologist must be given at least two weeks’ notice by the Link Alliance that works are about to begin. The Alliance shall keep the Project Archaeologist informed as to the work schedule and any changes that may arise. As set out in sections 6.4, 6.5 and 6.6 of this HC DWP (Archaeology Section), the Link Alliance will temporarily cease works and call-in the Project Archaeologist if suspected archaeological remains are exposed during works when an archaeologist is not present, so that the remains can be assessed and recorded. As set out in sections 6.5 and 6.9 of this HC DWP (Archaeology Section), the Link Alliance will give the Project Archaeologist sufficient time and opportunity for the recording and sampling of any archaeological features or deposits encountered, and will not resume clearance works in the immediate vicinity until the archaeological work is completed.

Training 5.1 Pre-Construction Briefing
Prior to the start of Mt Eden Enabling Works, the Project Archaeologist will provide a briefing on the archaeological requirements as contained within this section of this HC DWP (Archaeology Section) to the Link Alliance and all staff working on the Project. These requirements include but are not limited to: • • • •
Statutory requirements under the HNZPTA; How to recognise archaeological material (of pre-1900 or early 20th century date) if exposed during excavation works; What actions need to be taken should any archaeological material or remains be exposed or encountered; and Who to contact in the event of archaeological material being exposed, if the Project Archaeologist is not present on site at the time.
Mana whenua representatives will also be invited to provide a briefing on cultural requirements in case archaeological remains relating to Māori occupation are exposed during the clearance works.
5.2 Toolbox Talks The Project Archaeologist will attend toolbox meetings as required by the Construction Manager during the course of the works, the purpose of which will be to remind staff of the Project’s archaeological requirements and to ensure that any new staff joining the Project team are fully briefed prior to the commencement of works.
5.3 Training Records A record of attendance at briefing and training sessions will be held by the Environmental and Sustainability Manager as part of the Project training record (refer to the CEMP for further detail in this regard).

Archaeological Procedures and Mitigation Measures 6.1 6 Flower Street
The Project Archaeologist (or other qualified archaeologist under their direction) will be present to monitor any surface clearance and excavations within the property at 6 Flower Street (see Figure 6-1). If any subsurface archaeological features (of pre-1900 or early 20th century date) are exposed, they will be investigated, sampled and recorded by the archaeologist in line with the protocols identified in Sections 6.4 to 6.11 of this HC DWP (Archaeology Section) and the requirements of the HNZPT Authority.
6.2 31 Shaddock Street The Project Archaeologist (or other approved archaeologist) will be present to monitor any surface clearance and excavations within the property at 31 Shaddock Street. If any subsurface archaeological features (of pre-1900 or early 20th century date) are exposed, they will be investigated, sampled and recorded by the archaeologist in line with the protocols identified in Sections 6.4 to 6.11 of this HC DWP (Archaeology Section).
6.3 19 Shaddock Street The Project Archaeologist (or other approved archaeologist) will be present to monitor any surface clearance and excavations within the property at 19 Shaddock Street. If any subsurface archaeological features (of pre-1900 or early 20th century date) are exposed, they will be investigated, sampled and recorded by the archaeologist in line with the protocols identified in Sections 6.4 to 6.11 of this HC DWP (Archaeology Section).
Figure 6-1: Locations of the three properties to be monitored during the enabling works (red outlines) Page 14
| Mt Eden Enabling Works
Historic Character Delivery Work Plan (Archaeology Section)
6.4 Archaeological Discovery Protocols As noted in Section 3.1, there is only limited potential for subsurface archaeological remains to be exposed elsewhere during the Mt Eden Enabling Works. However, the possibility that archaeological features and deposits may be exposed during works will be managed and mitigated by call-in of the Project Archaeologist by the contractor; the recording of any remains exposed; and the recovery of samples of archaeological material for further analysis. If suspected archaeological remains (of pre-1900 or early 20th century date) are encountered, works will stop in the immediate vicinity of the find until the Project Archaeologist can assess the site.
6.5 Management of Archaeological or Cultural Remains Once in situ archaeological features or deposits (of pre-1900 or early 20th century date) have been confirmed the Project Archaeologist will advise the Project Manager and works will not resume in the immediate area until the necessary archaeological investigation and recording has been completed. The Project Archaeologist (or other qualified archaeologist acting under their direction) will investigate and record the remains, in accordance with accepted archaeological practice as set out in Sections 6.7 to 6.11 of this HC DWP (Archaeology Section) and the requirements of the HNZPT Authority. If remains indicating Māori occupation are exposed the protocols outlined in Section 6.6 of this HC DWP (Archaeology Section) will be followed. If significant archaeological features or deposits are identified during the enabling works the Auckland Council (Cultural Heritage Implementation Team Leader and Compliance Monitoring Officer), HNZPT and mana whenua will first be notified by the Project Archaeologist, and the remains will then be investigated and recorded in accordance with accepted archaeological practice and as directed by HNZPT, if of pre-1900 date. Any significant remains of 20th century date will also be investigated and recorded as directed by the Auckland Council (Cultural Heritage Implementation Team Leader).
6.6 Mana Whenua Protocols 6.6.1. Archaeological Remains If archaeological remains relating to Māori occupation are exposed, the Project Archaeologist will inform the appropriate mana whenua representatives.
6.6.2. Kōiwi Tangata (Human Remains) If bone material is identified that could potentially be human, the following protocol will be adopted: • •
•
Page 15
Earthworks/investigation will cease in the immediate vicinity while the Project Archaeologist (or other approved archaeologist) establishes whether the bone is human; If it is not clear whether the bone is human, work shall cease in the immediate vicinity until the Auckland University reference collection and/or a specialist can be consulted and a definite identification made; If bone is confirmed as human (kōiwi tangata), the Project Archaeologist will immediately contact the mana whenua representatives, HNZPT, the NZ Police Auckland Central crime | Mt Eden Enabling Works
Historic Character Delivery Work Plan (Archaeology Section)
• •
• •
•
squad and Auckland Council (Cultural Heritage Implementation Team Leader and Compliance Monitoring Officer); The site will be secured in a way that protects the kōiwi as far as possible from further damage; Once the NZ Police and HNZPT are satisfied that the remains are archaeological, consultation will be undertaken between the mana whenua representatives, the HNZPT Regional Archaeologist, the Auckland Council Cultural Heritage Implementation Team and City Rail Link Limited (CRLL) to determine and advise the most appropriate course of action. No further action will be taken until responses have been received from all parties, and the kōiwi will not be removed until advised by HNZPT; The mana whenua representatives will advise on appropriate tikanga and be given the opportunity to conduct any cultural ceremonies that are appropriate; If the mana whenua representatives are in agreement and so request, the bones may be further analysed by a skilled bio-anthropological specialist prior to reburial, in line with the HNZPT Guidelines Kōiwi Tangata Human Remains (2010); and Activity in that place can recommence as soon the bones have been reinterred or removed and authorisation has been obtained from HNZPT.
6.6.3. Taonga (Māori Artefacts) Māori artefacts such as carvings, stone adzes, and greenstone objects are considered to be taonga (treasures). These are taonga tūturu within the meaning of the Protected Objects Act 1975. Taonga may be discovered in isolated contexts, but are generally found within archaeological sites. If taonga are discovered the following protocols will be adopted: • •
•
•
•
The area containing the taonga will be secured in a way that protects the taonga as far as possible from further damage, consistent with conditions of the HNZPT Authority; The Project Archaeologist will then inform HNZPT, Auckland Council Cultural Heritage Implementation Team and the nominated mana whenua representatives so that the appropriate actions (from cultural and archaeological perspectives) can be determined; These actions will be carried out within the stand down period specified in Section 6.9 of this HC DWP (Archaeology Section), and work may resume at the end of this period or earlier if advised by HNZPT or the Project Archaeologist; The Project Archaeologist will notify the Ministry for Culture and Heritage of the find within 28 days as required under the Protected Objects Act 1975. This can be done through the Auckland War Memorial Museum; and The Ministry for Culture and Heritage, in consultation with mana whenua, will decide on custodianship of the taonga. If the taonga requires conservation treatment (stabilisation), this can be carried out by the Department of Anthropology, University of Auckland (09-3737999) and would be paid for by the Ministry for Culture and Heritage. It would then be returned to the custodian or the Auckland War Memorial Museum.
6.7 Recording of Features and Deposits Any in situ pre-1900 or significant 20th century archaeological deposits or features exposed during the Project will be investigated, recorded and sampled consistent with accepted archaeological practice and in accordance with the requirements of the HNZPT Authority. Detailed notes of each feature and deposit will be made, photographs will be taken, and all subsurface features located will Page 16
| Mt Eden Enabling Works
Historic Character Delivery Work Plan (Archaeology Section) be detailed on the site plan. Stratigraphic drawings and photographs of features and deposits will be undertaken. Sufficient time and opportunity will be allowed for the recording and sampling of any archaeological features or deposits encountered (see section 6.9). The archaeologist(s) will record the archaeological feature(s) or deposit(s) as quickly as possible so that works may resume without undue delay.
6.8 Artefact Management Plan The locations of artefact deposits will be marked on the site plan and retained for analysis. If large numbers of artefacts relating to European occupation are exposed, a representative sample will be retained. The process for storage, analysis and display shall be as follows: • • •
• •
Artefacts will be bagged, labelled by date and context, and may initially be stored in a secure on-site lock-up facility provided by the contractor; As soon as is feasible, artefacts will be transferred to the Project Archaeologist’s offices for cleaning, recording and analysis; Any significant artefacts and/or artefacts meriting public display, will be identified by the Project Archaeologist and, in consultation with relevant stakeholders, will be considered either for display within the new Mt Eden Station or for donation to the Auckland War Memorial Museum, as appropriate; Any wooden or fibre artefacts of significance will be wrapped/contained as required for short term preservation and analysis; and Less significant finds will be disposed of following recording and analysis, subject to CRLL agreement, unless a museum is willing to accept the collection.
Artefacts will be conserved by appropriate specialists if this is recommended by the Project Archaeologist based on the level of significance and suitability for display or addition to museum collections. Any Māori artefacts that meet the criteria of taonga tūturu under the Protected Objects Act 1975 will, in addition, be managed as set out under the Mana Whenua Protocols (Section 6.6.3 of this HC DWP (Archaeology Section)).
6.9 Stand Down Periods Depending on what is revealed by the Mt Eden Enabling Works, stand down periods involving the ceasing of works in the immediate vicinity may be required at various stages to allow for archaeological work to be carried out or for consultation with the appropriate parties. Stand down will require clearance works to cease only in the immediate vicinity of the feature or find, and work may proceed in other areas. The maximum stand-down periods in Table 6-1 will apply but works may be resumed earlier if the required work has been completed. Timeframes need to be flexible enough to ensure that archaeological works are completed as necessary to ensure that the procedures in this HC DWP (Archaeology Section) and the conditions of the HNZPT Authority are met.

Up to three days for a response from Auckland Council Cultural Heritage Implementation Team if significant post-1900 historic heritage remains are found, and in most circumstances up to three days for any detailed investigation required.
The likely requirement is a mitigation investigation and/or recording by standard archaeological techniques, but this will be advised by HNZPT, or by Auckland Council Cultural Heritage Implementation Team if the find is of 20th century date. Note that there may be special circumstances in which a longer period of stand down for investigation is deemed necessary by either HNZPT or Auckland Council.
Work resumes when the Project Archaeologist (and the Council’s Compliance Monitoring Officer in the case of post-1900 remains) advises the site foreman that work is completed.

As agreed between the project manager, HNZPT, Auckland Council and mana whenua.
HNZPT and NZ Police to be satisfied that kōiwi identification is correct. Mana whenua representative(s) to organise reinterment or removal of bones from site and appropriate cultural ceremonies.
Work resumes following reinternment or removal of bones from site and when authorisation from HNZPT and the Council’s Compliance Monitoring Officer has been received.
Taonga or archaeological remains of Māori origin found
Up to three days
HNZPT and mana whenua representative(s) to be consulted on appropriate action. Archaeological recording as required.
Work resumes when the Project Archaeologist or HNZPT advises the site foreman that work is completed
6.10 Post Excavation Analysis and Archiving Artefacts and faunal material retained from the site will be analysed and recorded by the appropriate specialists with the results presented in the final archaeological report, which will be provided to the parties specified in Section 6.11 of this HC DWP (Archaeology Section) for information and archiving.

Historic Character Delivery Work Plan (Archaeology Section) Depending on what is exposed, consideration will be given to displaying archaeological material such as artefacts within the new Mt Eden Station, as per Section 6.8 of this HC DWP (Archaeology Section). Any artefacts of significance relating to European occupation of the area that are recovered from the site that are not required for display may be offered to the Auckland War Memorial Museum in consultation with the Link Alliance. Any Māori artefacts (taonga tūturu) will be dealt with in accordance with the Mana Whenua Protocols outlined in Section 6.6 of this HC DWP (Archaeology Section) and the requirements of the Protected Objects Act 1975. Archaeological material identified by the Project Archaeologist as being appropriate for Carbon 14 dating will be sent to the University of Waikato’s Radiocarbon Dating Laboratory for age determination.
6.11 Reporting Requirements During the course of the Project, information on any archaeological discoveries will be provided to the Auckland Council (Cultural Heritage Implementation Team and the Compliance Monitoring Officer), HNZPT and mana whenua. Opportunities for provision of information to the public via on site and media releases will be taken in consultation with those parties, depending on whether any significant archaeology is exposed during earthworks. In compliance with the requirements of HNZPT Authority, a written summary report will be provided by the Project Archaeologist to the Link Alliance, HNZPT, Auckland Council (Cultural Heritage Implementation Team and the Compliance Monitoring Officer) and mana whenua within 20 days of the completion of the Mt Eden Enabling Works. A full and final monitoring report will be completed within 12 months of the end of the CRL project works, and will be provided to the Link Alliance, HNZPT, the Auckland Council (Cultural Heritage Implementation Team and the Compliance Monitoring Officer) (for inclusion in the Cultural Heritage Inventory), the NZ Archaeological Association Central File, mana whenua and any other parties specified in the CRL designation conditions and the HNZPT Authority. On completion of the final report, the Project Archaeologist will update the archaeological site records on the New Zealand Archaeological Association (NZAA) Site Recording Scheme (ArchSite database) and Auckland Council Cultural Heritage Inventory with a summary of the results and reference to the final report. Depending on the significance of the archaeological information recovered, articles may be submitted to academic journals for publication.

Appendix A: HNZPTA Requirements In addition to the requirements of the CRL designation, and this HC DWP (Archaeology Section) prepared in accordance with CRL designation condition 42, all modification and investigation of pre1900 archaeological remains are subject to the archaeological provisions of the Heritage New Zealand Pouhere Taonga Act 2014 (HNZPTA) and must be carried out in accordance with the conditions of an Authority issued by HNZPT under that Act. A general Authority for the Aotea Station to Mt Eden Station/NAL works, including modification of any subsurface remains exposed by the Mt Eden Enabling Works including the CSA, has been granted by HNZPT (Authority No. 2017/793). The Authority sets management procedures in place for archaeological discoveries. Care has been taken to ensure that the archaeological procedures set out in this DWP are consistent with the conditions and requirements of the Authority issued by HNZPT.

Stand Down Periods. This section states that “timeframes need to be flexible” and section 6.7 states that “sufficient time and opportunity will be allowed for the recording and sampling of any archaeological features or deposits encountered.” However, Table 6.1 provides for Maximum Stand Down Periods, which is incompatible with flexible timeframes and sufficient time and opportunity. Row 1 syas both “Maximum 2 days” and “Sufficient time.” If sufficient time turns out to be 3 or more days, this results in a lack of certainty for the project. Condition 3 of HNZPT authority 2017/793 states that “All archaeological evidence encountered during the exercise of this authority must be investigated, recorded and analysed in accordance with current archaeological practice.” Current archaeological practice is potentially time consuming

The contents of Table 6.1 are consistent with the Archaeological Management Plan approved under the Heritage NZ Authority (2017/793) and have been standard for previous Authorities and Heritage Management Plans approved by Council for other projects of this type, where extensive archaeological remains are not expected (i.e. in modified urban environments). We do not consider there is incompatibility between the fact that the contractor’s timeframes need to be flexible, and the maximum stand down periods given, as the necessary flexibility sits within those timeframes. Only limited remains are likely to be encountered during the enabling works, and 2 days has always proved sufficient for the archaeological team to investigate and record any feature encountered in such modified urban contexts, in accordance with current archaeological practice. No change has

and, while it is understood that the archaeologist will make very reasonable effort to clear the area as quickly as possible, this may not always be possible within the time frames outlined on Table 6.1. This table also states “Note that there may be special circumstances in which a longer period of stand down for investigation is deemed necessary by either HNZPT or Auckland Council.” This is potentially confusing. I suggest that Table 6.1 be changed to Stand Down Triggers, the second column deleted and the table reformatted to include relevant HNZPT, Council and mana whenua response times. The Archaeological Management Plan should be also be updated under Condition 1 of authority 2017/793.
therefore been made to Row 1 of the table. In Row 2 column 2 of the table relating to significant discoveries, the stand down period is: “Up to three days for a response from HNZPT for pre-1900 remains, and in most circumstances up to three days for any detailed investigation required. Up to three days for a response from Auckland Council Cultural Heritage Implementation Team if significant post1900 historic heritage remains are found, and up to three days for any detailed investigation required.” Note that the wording for pre-1900 remains states ‘in most circumstances up to three days’, while the Requirements column states that “there may be special circumstances where a longer period of stand down for investigation is deemed necessary by either Heritage NZ or Council”. We consider these statements to be consistent and compatible, with column 3 providing the explanation for the proviso in column 2. However, we have amended the second paragraph of Row 2 column 2 to provide a similar proviso to post-1900 remains, as this was not consistent with the statement in column 2. We do not consider that any changes need to be made to the Archaeological Management Plan issued under Authority 2017/793, as this table remains unchanged except where it relates to Auckland Council requirements.
C3 Auckland Council Comments The Council reviewer noted that in Section 1.2 the reference should be to designation conditions 41.1 and 42, not 42 and 43. This has been corrected, and the reference to 41.1 has been added to Table 1.1. The Council also requested that in Section 3.1 the word ‘demolished’ be replaced with ‘removed’ as the decision has now been made to relocate rather than demolish the building. This change has been made.
