OECD pension age comparisons
In New Zealand to be eligible for NZ Super you need to be at least 65 years of age. Currently 70% of the OECD has a pension age of 65 or lower. While countries are increasing their pension age, the majority are only moving the age up to 65 over the next four decades. This means that by the 2060s 60% of OECD countries will still have pension ages of 65 or below.
