The Deputy Leader of New Zealand First says his party will step in to stop management of the Waitakere Ranges morphing into co-governance. 

Auckland Council's proposing a board made up of Iwi, the Department of Conservation, and the council.  

Act Leader David Seymour has also criticised the plan as moving towards co-governance.  

Shane Jones told Mike Hosking they're not going to stand for it. 

He says they won't tolerate any slither of the West Auckland heritage land being under that type of arrangement.
