The working party recommended the number of councillors be reduced from 12 to 10. The mayor and councillors would continue to be elected at large by registered voters across the district.
The other recommended change is the establishment of a second community board, in addition to the existing Lakes Community Board. The objective of the new Rural Community Board would be to provide a voice specifically for the district's rural community.
The working party comprised councillors - Merepeka Raukawa-Tait, Tania Tapsell and Mr Sturt, and community representatives - Aroha Bray, Brian Eagle and Jill Nicholas.
The formal community consultation programme will take place between September 1 and October 2, with a final decision to be made in November.
That decision will be followed by a public appeal period, with the outcome of appeals being determined independently by the Local Government Commission by April next year.
The outcome will take effect from next year's local government elections.
