Employers are calling for a bipartisan approach to KiwiSaver and say "constant fiddling" by politicians worries them.
The Government is considering automatically enrolling workers who don't have KiwiSaver accounts because it wants more people in the scheme, but has ruled out making it compulsory.
At present people are automatically enrolled when they start work or change jobs, the change would mean those who haven't changed jobs would be enrolled with the same opt out provision.
The Employers and Manufacturers Association (EMA) said today certainty was an important principle in any retirement policy and it would be "very helpful" if National and Labour had a common approach.
"As it is, we're finding the constant fiddling with KiwiSaver by politicians is a significant cause for employer concern," EMA employment services manager David Lowe said.
