About the committee
The Waimakariri Zone Committee was established in mid 2010 as part of the Canterbury Water Management Strategy.
The strategy established 10 water zone committees in Canterbury – each with a local committee – with the Regional Committee working alongside zone committees and communities for positive outcomes.
The Waimakariri Zone Committee operates as a joint committee of Waimakariri District Council and Environment Canterbury.
Zone committee members are appointed for a three year term, after which a new committee will be formed. Applicants were assessed on skills, expertise, and experience as well as their ability to work together to develop water management solutions that deliver economic, social, cultural and environmental issues.
