National has said its tax cuts will be funded by proposed changes to KiwiSaver contributions.
The changes could make the scheme more attractive to those who can not afford 4 percent of their income.
Under Labour a 25 year-old on the average wage could save close to $400,000 by the time they turn 65, while under National the same worker would have 231,000.
"Well it is a better deal under Labour's plan than National's but it still an awfully good deal, the best place for nearly everybody to save and so everybody under 65 should really be looking hard at it, " Says KiwiSaver Columnist Mary Holm.
But the Council of Trade Unions disagree.
It represents the interests of 350,000 workers and says National's plan to scale down contributions makes the scheme less attractive.
"Well we need long term savings, also KiwiSaver was a way we could get workplace savings moving and catching up with Australia. It's a good scheme over 800,000 have joined to take the axe to it is really disappointing," says Peter Conway from the NZ Council of Trade Unions.
Those who have signed up to KiwiSaver account for over a third of our total workforce.
It has proved so popular, even the government recently blamed it for adding to the current deficit.
And some believe changes are necessary.
"There's a little bit of pain there particularly for small business because the tax credits for employers go away, but it looks in the round like it's a much more sustainable solution that the solution we have here today," says Phil O'Reilly, Business NZ Chief Executive.
But it is doubtful that all of the 800,000 KiwiSaver's will agree with that.
