How the Whanganui District Council is made up - including the number of councillors - is up for review.
Whanganui currently has 12 councillors, a mayor and a six-person rural community board.
The review, required every six years, looks at the number of councillors to be elected, the basis of election for councillors - such as wards - and whether there are to be community boards in the district, where they might be, and what their membership arrangements are.
The last representation review was in 2018, with little change made to Whanganui’s existing local government structure.
Whanganui Mayor Andrew Tripe said community input was crucial, and a public survey opened this week and will run until March 10.
