New Zealand Superannuation will still be affordable in the future, provided the government keeps control of other spending, according to commerce minister Paul Goldsmith.
Goldsmith told international attendees of the NZ-OECD High Level Symposium on Financial Education that the cost of superannuation would rise from 5 per cent of GDP to 7 per cent of GDP by 2045.
The National-led government has ruled out increasing the age of eligibility for superannuation to help mitigate the increasing costs being driven by an aging population.
Other countries have already put in place plans to increase their retirement eligibility ages.
But Goldsmith said NZ Super was affordable.
