About Mangere catchment

Located north-west of Whangārei, the Mangere catchment is a mostly low-lying area of intensive agriculture. Its main river, the Mangere River, is a slow-flowing tributary to the Wairua River.

Mangere River's water quality results indicate it is one of the more impacted of Northland's monitored rivers. However trend analysis indicates that Mangere's water quality is getting better over time, and in 2014 the Mangere River was identified at the 2014 River Awards as the most improved river in Northland based on the long-term decline in dissolved reactive phosphorus levels.

While this is good news, there is still clearly substantial room for improvement in water management and this is the primary aim of the Mangere Catchment Group.

Catchment plan

The Mangere catchment group has developed a catchment plan to tailor the way fresh water is managed in the Mangere catchment. The catchment plan includes regulatory (i.e. rules) and non-regulatory water management measures – regulatory measures can be included in the new Regional Plan while non-regulatory measures will be set out in an implementation plan.
