New Zealand is rapidly ageing: Today there are about 870,000 Kiwis who are 65 or older, making up about 17% of the population. In 25 years, that number is forecast to almost double and make up about a third of the population.

As well as the pressure on universal superannuation and healthcare, the ageing population will also put infrastructure under strain. Researcher Kali Mercier has considered the implications in her new report, Age-proofing Aotearoa, published by the Helen Clark Foundation and WSP.
