Auckland Council is going ahead with plans to close pockets of the Waitakere Ranges Regional Park to protect kauri trees.
Twenty seven kilometres of track will be shut from July, in areas where the trees appear to be unaffected by kauri dieback - a fungal disease.
Parks, Recreation and Heritage Forum chairperson councillor Sandra Coney says the closures are precautionary to stop the disease spreading.
The protection zones are in the Cascade Kauri, Anawhata, Waiatarua, Piha, Karekare, Huia and Parau areas.
The effectiveness of the track closures will be reviewed after a year.
The council says it's tried to ensure there's still plenty of opportunity for visitors to the Waitakere Ranges to be able to walk and tramp.
There are over 250 kilometres of tracks in the ranges.
