The Government has ruled out buying a pristine beach in the heart of the Abel Tasman National Park, but says it may contribute money to a public campaign.
The privately owned Awaroa inlet is being sold through a tender process and is expected to reach at least $2 million.
A fundraising page has been set up on the Givealittle website, where people are being asked to donate money to make sure the seven hectare plot goes into public ownership.
So far more than $800,000 has been raised.
Conservation Minister Maggie Barry has promised that Awaroa will be added to the conservation estate if the online campaign is successful, saying it "would be a great gain for New Zealand".
She says officials are looking at different ways the government can support the bid.
"We're looking at the various funds that are possible but frankly when you've got a Government involved and the Crown sometimes people can see huge dollar signs … and we don't want that either," she says.
The Government has ruled out buying the land outright.
Tenders close in two weeks.
The idea for Kiwis to chip in to buy the beach is the brainchild of Christchurch man Duane Major.
Following a conversation with his brother on Christmas Day, he decided to create a Givealittle page and crowdsource money to buy the land for everyone to enjoy.
"I congratulate the organisers of the campaign and wish them all the best in their efforts," said Ms Barry.
