Labour is confident it can fulfill all its promises if it's elected this year, without raising taxes.
The party has today confirmed it won't be lifting personal taxes.
But leader Andrew Little said Labour will review the entire tax system, if it's elected.
"I'm confident that at least in the first term of government we can beat all those pledges without having to charge any more taxes."
Labour is also cranking up its commitment to make life easier for first home buyers.
Mr Little is promising to take a look at negative-gearing - used by investors as a tax advantage to buy residential property.
He said there is no reason for investors to have an edge over other buyers.
"It's first home buyers who need every bit of help they can get, and they will be our priority."
