Prime Minister John Key has signalled an increase in GST, across-the-board tax cuts and getting more tax out of property investors.
In his opening statement to Parliament Mr Key ruled out land and capital gains taxes, but said he was "carefully considering" increasing GST up to 15 percent to fund personal income tax cuts.
The GST increase would raise about $2 billion to fund the cuts and tax structure reform.
Labour leader Phil Goff has lambasted Mr Key after his announcement, saying his tax reform benefitted only those in the top tax bracket, and an increase in GST is a disadvantage to the poor.
