Finance Minister Bill English has revealed that any future tax cuts National looks at would be small and "a lot less than 20 dollars a week".
At a finance leaders debate in Queenstown tonight, Mr English said if National is re-elected "the amount of money available for that is relatively small".
"So if people are going to be expecting some package with 20 bucks a week...we are not going to be announcing anything like that before the election."
Conservatives leader Colin Craig also attended the "Great Debate", alongside Mr English, Labour's David Parker, the Green's Russel Norman, and Act's Jamie Whyte.
Mr Craig maintained his conservative view on foreign land ownership saying the for sale sign on New Zealand should be taken down, while Mr Whyte accused Mr Parker of over-simplifying property rights.
"We do not live in a communist country, it's about property rights," Mr Whyte said.
Immigration also featured in the debate, causing Mr Parker to tangle his comments about low value migrants.
"We've got a low value immigration...these good people who are the low value ones... people taking low value work," he said.
Mr English came under fire for his Government's refusal to reveal New Zealand's details of the Trans Pacific Partnership trade talks.
While the parties' spokesmen were there to talk finance, it seems there's no getting away from Dirty Politics.
Questions concerning details in Nicky Hager's book came after questions from the floor about honesty.
Next up, Prime Minister John Key will battle it out against David Cunliffe in the first televised leader's debate on Thursday night.
