As communities in Hawke's Bay consider local government reform options, a problem you have is how to avoid drawing the conclusion that amalgamation is the answer because that's what happened in Auckland.
This is a problem because it ignores the fact that Aucklanders had amalgamation imposed on them. Auckland was presented with a political "solution" - amalgamation of its seven councils - and made to justify it through a commission and "Super City" establishment process. Only after a divisive debate was it agreed to establish a tier of local boards, giving some recognition to community concerns about the size of the new city and desire for representation of Auckland's many communities of interest - rural and urban, multi-cultural make-up and distinctive lifestyles.
I note that other regions in New Zealand also have advocates for local government reform who have similarly started off their campaigns with an outcome - amalgamation (or not).
Reinforced by Auckland's experience - basically, the replacement of eight councils with one governing council, seven council-controlled organisations (CCOs) to deliver services and 21 local boards and a mayor with governance powers - I do not believe that starting from and debating a particular outcome builds a constituency. It hasn't in Auckland. Auckland's reform is far from settled and, this year, will see reviews begin on matters such as the role of the CCOs and the powers (or not) of local boards.
Hawke's Bay has a choice - to think outside the square - including investigation of options other than simplistic amalgamation. Instead, building a constituency for change is fundamental if change is to be successful.
