Modelling Group


The Water New Zealand Modelling Special Interest Group caters to all people involved or interested in Modelling in the water industry. The group is co-ordinated by an enthusiastic management committee which meets regularly to discuss promotion and support of industry best practice in water modelling through education, events, and guidelines.

The Modelling Special Interest Group facilitates events to provide education, knowledge sharing and networking opportunities. Our premier event is an annual modelling symposium. To be notified of this and other upcoming events, or to join the committee please fill out the contact form below.


The Water New Zealand Modelling Special Interest Group aims to:

  • Provide a forum for discussion between users of planning and management tools in the areas of stormwater, wastewater (reticulation and treatment), surface water (piped stormwater and rivers), groundwater and water supply (reticulation and treatment) and the coastal environment.
  • Facilitate the exchange of information between relevant organisations including operating and regulating organisations and other interested or experienced bodies.
  • Identify areas of improvement in the use of models as planning tools and their application through research and previous experience of the group.
  • Provide a mechanism through Water New Zealand for promoting excellence in the use of models as planning tools in the industry.
  • Organise symposiums and other meetings to fulfil the Group's objectives.
  • Report on progress and activities of the Group through Water New Zealand.

Membership of the groups is open to all Water New Zealand members. Activities of the group are overseen by a committee of up to fifteen group members and administered by Water New Zealand.

Committee membership is open to all group members, and new members are confirmed annually at the group’s Annual General Meeting.
