"More than 11,000 people have chipped in to the campaign because they care and they see access to as much of our coastline as possible as a birthright."
Last week, Conservation Minister Maggie Barry confirmed that the beach would be added to the Abel Tasman National Park if the online campaign to buy the land succeeded.
Today, Ms Barry said she had instructed conservation officials to speak to the organisers of the campaign about the legal requirements for making the beach part of the national park.
If the target were reached, free access would be secured for the public in perpetuity.
The campaign was started by Christchurch resident Duane Major, who regularly visited the beach.
The Department of Conservation has previously said that it is not interested in buying the spot because it is not considered a precious ecological site, but it would be open to receiving the land as a gift.
A spokesman said the department could not justify spending $2 million on 800m of beach and a section of kanuka scrub.
Tenders for the sale close on February 16.
