The New Zealand Superannuation Fund is a sovereign wealth fund in New Zealand. New Zealand currently provides universal superannuation for people over 65 years of age and the purpose of the Fund is to partially pre-fund the future cost of the New Zealand Superannuation pension, which is expected to increase as a result of New Zealand's ageing population. The fund is a member of the International Forum of Sovereign Wealth Funds and is therefore signed up to the Santiago Principles on best practice in managing sovereign wealth funds.[7]
