National's Kiwisaver promise could help address a gender savings gap.
The party is committing to raise minimum contributions and make employers contribute for staff over 65, if re-elected in November.
It would also make Kiwisaver compulsory - promising a $1500 boost for every newborn.
Milford Asset Management's General Manager of KiwiSaver, Murray Harris told Mike Hosking that staff on paid parental leave will also get contributions.
He says on average female balances are 25% lower than male, because they usually raise the children and miss out on contributions.
