First started as the Auckland Superannuitants Association, Grey Power is a voluntary organization founded in February 1986 by a group of superannuitants protesting against the imposition of a surcharge on New Zealand Superannuation. Grey Power is now a federation of associations from across New Zealand.
The individual Grey Power Associations are all duly Incorporated Societies under their own right and together they form the Grey Power New Zealand Federation Inc: the National body of some 74 Associations throughout the country with a combined membership fluctuating up to 90,000 members.
While the original reason for forming the movement was the opposition to the surcharge on New Zealand Superannuation, Grey Power now works in all matters pertaining to NZ Superannuation, as well as in the areas of Aged Care, Energy and many more. These areas of importance are allotted to Board subcommittees as National Advisory Groups.
