Council and contractors would be working in the area for at least two more weeks, and Gregory asked people to keep out of fenced-off areas of the lower carpark, where slips were undercutting the carpark edge.
The upper and lower carparks would remain closed while stability testing is conducted during the next two to three weeks, Gregory said.
Memorial Drive would remain closed to traffic for several months at least, until slips stopped moving and a solution to permanently secure the road was in place.
Council was establishing carparking facilities at the locked gate, and expected to reopen the rest of Memorial Drive to walking and cycling traffic by March 21, Gregory said.
Anyone cycling on the lower mountain bike track to Spider Junction was warned to be alert and aware it was a constantly changing environment.
The council’s message to stay away from the slip-affected area was supported by Te Kahu o Torongare.
