The Government stepped in with a $350,000 pledge to help get Abel Tasman beach bid over the line.
The successful Givealittle bid to buy Awaroa Inlet beach was announced this morning and supported by more than 39,000 people who pledged more than $2 million.
Confirming the Government's pledge, Conservation Minister Maggie Barry said: "Duane Major, Adam Gard'ner and the almost 40,000 Kiwis who donated close to $2 million to buy Awaroa beach deserve the thanks of the nation for their generosity, energy and spirit.
"It's been inspiring to see how the campaign reflected New Zealanders' deep connection to our land and our desire to see it protected.
"As the Prime Minister said during the appeal, the Government was ready to step in with a modest contribution if needed."
The funding would be allocated from the Nature Heritage Fund, which enables the acquisition of land for the conservation estate.
Ms Barry said the process from here is for the campaigners to set up a trust or holding company to hold the land until it can be gazetted as part of Abel Tasman National Park and enter Crown ownership.
"I've asked officials to do the necessary consultation and paperwork as quickly as possible. Once it becomes part of the National Park, access to the beach will be secured for the public in perpetuity."
A Givealittle spokeswoman told the Herald this afternoon that they are currently in the process of finalising all the details of the fundraising campaign. They will then directly email every person that pledged money.

"From there we will start processing the pledges and we'll let people know in the email exactly what we're going to do."
Because the beach fundraiser was a Givealittle "project" rather than a "cause" it means no money has been drawn yet, she said.
Instead people have provided their credit card details and have made a commitment to pledge.
The emails will be sent out today and will seek confirmation that people are ready for the money to be withdrawn from their account.
The spokeswoman said with all Givealittle projects, there is always a risk of people backtracking on their pledges.
"But we know with this - people really want to be a part of it, and in fact we've had lots of people call and say 'I missed the deadline, can I still contribute'. So we expect that [people back-tracking] will be a very small amount, but there's always an element of that with any cause or any project.
"So that's been taken into account from the beginning, we have a process for managing that."
Campaign organiser Duane Major said this morning of their victory: "We have pulled it off, we have pulled it off. At 10.57 last night we delivered a pristine piece of beach and bush into the hands of all New Zealanders to look after and cherish and treasure forever.
"My heart is beating and I've got goosebumps and I'm just so thankful for all those people. What a crazy journey."
Mr Major revealed that the final amount raised by the public was $2,278,171.09.
"I always thought we could do it. You think about the heartbeat of New Zealanders and you think about the numbers. I did not anticipate the crazy, freakish nature of this campaign but boy is this rewarding. It's satisfying to actually pull it off and to take those ideas and hunches and feelings and to put it into practice."
He said the victory had left them with a deep down sense of satisfaction. "We've done something very special I believe."
