Rob Hutchison, Ngati Whatua Whai Rawa chief executive, explained the huge remediation plan.
"We are in the planning stage of significant remediation works at Eastcliffe on Orakei. These works ... will be undertaken over a five-year period. The value of Eastcliffe on Orakei has fallen to reflect the need for these works," he said.
The village, near Mission Bay at 217 Kupe St, faces Ngati Whatua's Bastion Pt and its marketing says it has 25 completed independent townhouses and 33 apartments. It also has studios and hospital rooms.
According to its marketing material, Eastcliffe "is not a retirement home, nor a retirement village. We are a retirement resort. And when you see the facilities ... you'll understand why our residents say 'it's like being on holiday every day'."
Facilities include a 12m heated indoor swimming pool with sea views, heated spa, gym, restaurant with resident chef, indoor bowls, bar facilities/sports lounge, craft room, library, hairdresser and dance floor.
