MAHURANGI RIVER RESTORATION

The North Island’s historic Mahurangi River is to be dredged and returned to a navigable condition.

Over many years siltation from farming, forestry and human activities has built up to the extent that continued all-tide access has become impossible. Vessel movements are now restricted to approximately two hours either side of the high tide.

Auckland Council’s resource consent allows dredging to a depth of 1.50m below chart datum. Apart from reopening the river to navigation, it is believed the increased tidal flow will help clean and improve the water quality in the river.

A plan has been approved to use the spoil from the dredging on a designated land site in the Mahurangi district, which avoids any dumping of sediment at sea.

Estimated cost is $4million and it is expected the project will take about three years – less if early funding is achieved. The Mahurangi River Restoration Trust will be making applications to funding organisations, but is also seeking support from the public and the boating community.

Two purpose-built shallow draft tugs and a large barge with excavator are operating in the river.

The river is an historic stretch of water and for many years was navigable from its mouth to Warkworth.
