"Given the universal support, this research shows we now need to have a constructive policy debate on contribution levels and how we can increase them in a sustainable manner," Klipin said.
"It is important that these findings are given serious consideration at policy level."
A majority also supported the ability to choose automatic increases in contribution rates, and to have extra choices to raise contributions.
The ability to have extra choices was backed by the majority of supporters of all political parties, with 83 per cent of National, 64 per cent of Labour, 85 per cent of NZ First and 74 per cent of Green voters in favour.
Research also showed support for allowing those over 65 years of age to join KiwiSaver, and the decoupling of KiwiSaver access from pension age.
"The research provides an opportunity to understand New Zealanders views on the KiwiSaver scheme and how they want it to evolve," Klipin said.
"It's now up to industry and Government to take the findings on board and work to improve KiwiSaver."
