Conservative Party leader Colin Craig spent more than $1.6 million of his own money on the party last year.
Party donation returns for last year released today by the Electoral Commission showed Mr Craig continued to be the biggest single donor to any political party.
The National Party received $16, 850 from Museum Hotel owner Chris Parkin, $17, 850 from canned food distributor James Crisp, philanthropist Graeme Douglas gave $25,000, Fendalton man Cyril Smith donated $29,950, and Auckland Scholar Hotel and Apartments donated $24,000, Roncon Hotel Management $22,000.
Act Party president John Boscawen donated $24,000 of his money to his party, and it received a total amount of $52,570.
Green Party MPs gave their own party $233,487, including $17,664.88 and $17,364.88 from the party's leaders.
Labour received a bequest from of $430,259.33 from the estate of Brian James Dalley. That and other donations came to $270,423.93
The returns showed Labour breached the electoral law by failing to file a return for the bequest within the 10-day period but the party will not be prosecuted.
The commission said it had enquired into the breach but did not intend to take the matter further.
A spokeswoman for the commission said Labour explained the donation was the first bequest received by the party for some years and the party's general secretary Tim Barnett and his predecessor had not been aware the bequest needed to be treated like a donation for the purposes of the Electoral Act.
The Labour Party had changed its financial processes for the management of bequests and subsequently filed a late return for the donation.
The Electoral Act states donations over $15,000 have to be disclosed only once a year, while a return needed to be filed within 10 working days for any donation over $30,000.
A party secretary can be fined up to $40,000 for not filing a return if they don't have a reasonable excuse.
