Whangārei District Council is asking people to stay off Parihaka on the weekend due to dozens of slips affecting the mountain.
The top part of Memorial Drive has been locked off and Parihaka is closed until Wednesday, March 1.
Council spokesman Peter Gregory said people needed to keep off all tracks on the town side, but the lower bike track on the Whareora side could be used by cyclists as far as Spider Junction.
“Many of these slips are still on the move and we don’t want anyone to get hurt,” he said.
“We are installing a locked gate about 800m before the lower carpark on Memorial Drive to stop vehicles. We don’t want people to walk past the gate for now.”
