"We have been taught to prepare for our retirement in other ways, whether it be KiwiSaver or private pension funds."
Mr McGrath and his wife have plans in place with private pensions, KiwiSaver and a rental portfolio.
"I think most people who are under 42 aren't expecting to live off the state when we retire and so whether it is 65, 67 or even older by the time we retire it won't really matter," he said.
"Anything extra, in terms of superannuation from the government, will be a bonus."
However 38-year-old Viktor Galyer isn't pleased with the decision.

"I don't like it, I don't want to work till I'm 67," he said.
"They're making a change even though looking at the statistics they don't necessarily need to."
Mr Galyer said he had KiwiSaver, but that would go towards buying a house first, so he had not started saving for retirement.
"It's crazy that the flag was such a big deal, but this was done so quickly we didn't even really know about it," he said.
Sonia Te Whare, born in 1967, will be unaffected by the change, but can understand people are feeling ripped off.
"It doesn't really bother me, because for me personally it will be fine," she said.
"They already moved the goalposts when we were in our 30s, from 60 to 65."
Her co-worker Michelle Davies falls just within those affected, born in August 1972, and will have to work an additional six months before she is eligible for the pension.
"They've made it hard for our generation to get themselves set up financially and I guess it gives people two more years.
"I feel sorry for people in the line of work where it's quite physical."
