If I understand what your saying correctly, making Kiwisaver compulsory would be an essential part of changing national super. At least then people are forced to make some sacrifice. Also with Kiwisaver the money is put aside for your retirement unlike Roger's spurious suggestion people have paid in all their lives. That unfortunately is not the case. People have been paying taxes all their lives, yes, unfortunately very little was put aside to pay national superannuation so you will be relying on future generations to pay it. You could suggest the older generation has already spent all the taxes they paid, on themselves and now require the next generation to fund their retirement.
