Your basic NZ Superannuation entitlement is not affected by what assets you own or where you live. You can live in your own home, or elsewhere, with no penalty.
Work and Income New Zealand (WINZ) does offer a range of financial support measures which may be of interest if you are 65 or older. These include the Accommodation Supplement, Residential Care Subsidy and Residential Care Loan (to help you keep your home if you enter a rest home). Speak with
WINZ or a financial advisor to find out if you are eligible for any of these support measures.
