Porirua Mayor Nick Leggett and Greater Wellington Regional Council chair Fran Wilde said the decisions made by both councils were an important part of starting what will be significant discussions with the Wellington region's communities about local government arrangements.
"This process is not just about structures, although a recommendation from the panel about a preferred structure will be an outcome," said Mr Leggett.
Ms Wilde said they were fortunate to be able to secure the services of four outstandingly well qualified New Zealanders to complete the review.
The panel has till the end of October to deliver the two councils a report recommending what they conclude is an appropriate set of organisational arrangements for local government in the region.
