Awaroa Beach becomes part of the Abel Tasman National Park today after 40,000 Kiwis raised the money to buy it - but local Maori want the Government to hand it on to them.
At least 200 people are expected to turn up by boat and on foot at midday for the handover of the remote beach, which sits in the middle of Abel Tasman National Park.
The beach was privately owned by European families until it was bought for the nation with $2.3 million donated through a Givealittle campaign last summer.
Wakatu Incorporation chairman Paul Morgan, who will speak for local iwi at the handover, said the 7ha beach property should not have been taken from its original Maori owners.
"Our view hasn't changed, the Government is in possession of land that actually belongs to Maori," he said.
