New polling data has revealed less Kiwis have faith the current Government can turn the economy around ahead of the upcoming election.

A New Zealand Herald-Kantar poll has found voters are evenly split on Labour's proposed capital gains tax and about 45 percent of respondents in an IPSOS survey scored the Luxon-led Government below 3 out of 10.

Finance Minister Nicola Willis says it's clear a significant number of people are still opposed to the capital gains tax and  the Government has plenty of time to expose the negative impacts.

"There's also a big, undecided group in the middle and those are the people that we will be speaking to between now and the election."
