There's hopes compulsory KiwiSaver can help New Zealand catch up to Australia's economy. 

The National Party is campaigning on making KiwiSaver mandatory for all workers, and for gradually raising the matching rate to six percent. 

NZ Herald Business Editor at Large Liam Dann says he wants to see a bipartisan effort and for the Labour Party to get on board. 

He says people will need to get used to that six percent figure. 

"They're at higher levels than that in Australia - it's painful in the short term, but they do cope. And then, you move on and then you forget about it and you just look at that giant figure on your KiwiSaver statement."
