In New Zealand, we have Government Super, which is set to 65% of the net average wage (1).
Of course, this is expensive, which is why we have the Government putting aside money into a sovereign wealth fund to help pay for it (2).
We also know that we should personally contribute if we want a better retirement, so we have personal retirement accounts, where the minimum contribution is 3% of salary, matched with 3% from your employer, plus ~$500 NZD from the Government (3).
