The Gibbs money takes Act's tally of big donations this term to $312,855, compared with National's $530,000 - of which $300,000 came from Aucklander Susan Chou, who donated that amount in three separate lots over the past two years.
Ms Chou and her husband, Zhaowu Shen, have business interests in NZ, Hong Kong and Vietnam and are long-time supporters of former National Cabinet minister Pansy Wong.
Labour took in $100,500 in major donations in the present term.
Donations of more than $15,000 must be disclosed in post-election and annual returns.
Meanwhile, there was some embarrassment for Act after its rivals noticed its website policy page was filled with Latin words and names of different cuts of meat.
The news of Act's "meaty manifesto" began to trend on Twitter, including meat-related puns and jokes about corned beef being listed given Dr Brash's fondness of it.
A spokesman for the party said the paragraphs were used by designers during a redesign of the website as fillers until the appropriate policies were put in place.
He said that page was not due to be "live" until today.
