According to new research, there's a significant gap between the KiwiSaver contributions of men and women.

Te Ara Ahunga Ora The Retirement Commission has released a report revealing that women contribute 36 percent less on average yearly than men.

Commission policy lead Dr Michelle Reyers says women are more likely to stop working to fulfil care-based responsibilities- or work in part-time roles.

"What we saw from this research is that women and men are actually contributing exactly the same percentage of their salaries- but when we look at the dollar value, that's where that big gap is coming from."
