Grey Power is one of the biggest lobby groups in New Zealand. It has been advocating for the elderly since 1986 and was originally formed to oppose a surcharge on New Zealand Superannuation.
It has now grown into a 90,000 member federation and with that kind of voting power it is increasingly listened to by the government.
Although the name suggests otherwise, you don't have to be grey or elderly to get involved. Grey Power members can participate fully from the young age of 50.
As well as political power, the group has a number of discounts for members including Cook Strait ferries and discounts on actual power bills.
