Special Interest Groups An introduction to the communities shaping our water sector


Kia ora, welcome Water New Zealand's Special Interest Groups (SIGs) are member-led communities that bring together people who share a passion for advancing different areas of the water sector. Open exclusively to Water New Zealand members, SIGs provide opportunities to build professional networks, share knowledge, discuss emerging challenges, and contribute to industry initiatives. Through events, working groups, resources, and sector conversations, SIGs play an important role in supporting collaboration and helping shape the future of water services in Aotearoa New Zealand. Whether you're looking to learn from peers, contribute your expertise, or stay connected with developments in your field, joining a SIG is a great way to get involved and make an impact. 2


About Water New Zealand Water New Zealand is the country’s largest water industry body and provides leadership in the water sector through collaboration, professional development and networking.

Water New Zealand promotes the sustainable management and development of the water environment.

SIG Roles While each SIG determines its own priorities and ways of working, there are a number of common roles found across most SIGs. These roles help ensure they are well governed, connected to members, and able to deliver activities that support their objectives.

Chair Provides leadership for the SIG and oversees the delivery of the group's work programme. Chairs committee meetings, represents the SIG where appropriate, and serves as the primary point of contact with Water New Zealand.

SIG Committee Members Work together to guide the direction and activities of the SIG. Committee members contribute ideas, lead initiatives, and help deliver events, resources and member engagement activities.

Water New Zealand Liaison Provides administrative and operational support to the SIG and its committee. They help coordinate meetings, communications, records, budgets and alignment with Water New Zealand processes.

SIG Members Water New Zealand members who have joined the SIG to stay informed and engage with activities. Members can participate in events, contribute ideas, and connect with others interested in the SIG's focus area. 7


SIG Roles Young Water Professional Liaison Acts as a connection between the SIG and the Young Water Professionals network. They help identify opportunities for YWP engagement, participation and collaboration in SIG activities.

YWP Steering Group They provide national coordination, leadership development, and strategic engagement opportunities for emerging professionals across the water sector.

Subgroup Chair / Friends of the Committee Lead Leads a subgroup or Friends of the Committee group and coordinates its activities and meetings. They act as the link between the subgroup and the SIG committee.
