An Australasian lobby group whose members work in the superannuation industry says KiwiSaver should be made compulsory because of growing demand.
Finsia, the Financial Services Institute of Australasia, commissioned Claire Matthews from Massey University to undertake research on KiwiSaver behaviour and engagement.
An online survey of more than 1000 people found the number of people wanting KiwiSaver to be made compulsory increased from 37 per cent to 43 per cent between 2011 and 2012.
More people also believed it should be compulsory for those who were employed and for all New Zealanders aged over 18.
Finsia chief executive Russell Thomas said the increase showed New Zealanders supported KiwiSaver membership being made compulsory.
