Zone Implementation Programmes

Zone Implementation Programmes - or ZIPs - were developed when water zone committees were established. These bits of work followed the adoption of the Canterbury Water Management Strategy and aimed to provide overarching goals for water management in the ten different water zones of Waitaha/Canterbury. 

While we may have moved on in terms of our priorities in each zone, ZIPs remain the foundation of the work we do.

Following the adoption of the Waimakariri Zone Implementation Plan Addendum (ZIPA), the committee worked with the community to develop additional actions to help address land and freshwater challenges in the zone. These were reflected in the ZIPA and were used to inform changes to the Canterbury Land and Water Regional Plan.
