NZ First leader Winston Peters has slammed the report as "shonky work" and the authors as covertly working as "lobbyists for the pension industry".
Three views from different generations
Generation Y
Max Nuttall, 20
Do you believe you'll have NZ superannuation when you retire?
I hope so. It's going well and they should leave it alone.
Do you think the super age will stay at 65?
I hope they do and I think they should keep the age at 65, it's late enough as it is.
People aren't retiring too late at the moment anyway - a few people I work with have just retired and they're only around 50 years old.
Have you started your own savings plan?
Yes. I'm on KiwiSaver and so far I've managed to save about $1500.
Generation X
Steve McLennan, 42
Do you believe you'll have NZ superannuation when you retire?
From the Government? I don't think so, no. I don't trust the Government not to put it back in their own coffers, so I think we are going to be up for some serious changes.
Do you think the super age will stay at 65?
I don't think it's sustainable, it's got to go up - I think it would be up in the mid-70s, because people are living longer.
But it's extremely worrying and we are going to have inter-generational warfare. We've had the baby-boomers lump a lot of debt on to younger generations and I think they are going to react badly when they start voting ... whenever that is.
Have you started your own savings plan?
No, I haven't started my own savings plan. We have investments in properties but I wouldn't call that a plan.
Baby Boomer
Elizabeth White, 55
Do you believe you'll have NZ superannuation when you retire?
I certainly hope so.
Do you think the super age will stay at 65?
I'm not sure but I think it could go up for people who don't have physical jobs. Some people burn themselves out because they have physical jobs, but if they're in office work
I think they could go on. It could go up to say, 67 or 68.
Have you started your own savings plan?
No, I don't have a savings plan. I've saved nilch.
