Labour's leader continues to call the Government tax cuts poorly timed.
The Government's pouring $14.7 billion into it and giving landlords a $3 billion boost.
The tax changes kick in late July against advice from officials who recommend waiting until October.
Chris Hipkins says 12 billion dollars has been borrowed to fund the cuts.
He told Kerre Woodham that he agrees tax brackets need adjusting, but you have to carefully choose when it's done.
Hipkins says this is the worst time to do it, with inflation high and Government revenue declining because of the economic downturn.
