The hefty sum has been raised by 9273 pledgers so far, with just over three weeks left to raise the remaining money.
Telecommunications company Spark has pledged $20,000 for the campaign.
Spark director Simon Moutter said if the $2 million wasn't raised, it would be a lost opportunity.
"Two million is a big ask for a small country like ours so at Spark we wanted to chip in and do our bit. We're encouraging other New Zealand businesses to join us. New Zealand only has a couple of weeks to secure this beautiful beach, otherwise the opportunity will be lost," Moutter said.
Although the beach was open for the public, Mr Major said that might not be guaranteed in the next 30 to 40 years as it had riparian rights.
"I want to make sure it can't be developed, as I enjoy and appreciate it so much. This beach is particularly beautiful."
The $2 million would need to be pledged before the tender closes on February 16 at 4pm.
