Asked if that was hypocritical given the Labour Party had introduced stricter donation disclosures for general elections and criticised National for its lack of transparency, Mr Barnett said it was for an internal party procedure rather than an election.
He would not say how much was passed on to the party's coffers but said if any candidates provided more than the disclosable limit of $15,000 for party donations, it would be declared in its return in April. Any such donations would be declared as from the contestant rather than the donors who originally gave the money.
The Electoral Commission confirmed Labour would not have to disclose the original donors because the donations were for an internal party matter rather than an election. In effect, that process could allow Labour to get around donation disclosure rules by filtering significant donations through a leadership contestant, although Mr Barnett said that was not the intention.
In a bid to prevent National filtering donations anonymously by using trusts, Labour introduced new donations disclosure rules in 2005.
