Former Kaipara District Council commissioner Peter Winder has been retained to manage outstanding legal issues including a long-running court case involving Mangawhai ratepayers.
He was one of three commissioners appointed by the Government in September 2012 to help Kaipara resolve its $80 million debt that arose from the controversial wastewater scheme, and other serious governance issues.
Former National MP John Robertson was the chairman of commissioners while Titoki farmer Richard Booth and Colin Dale were the other commissioners.
Mr Dale quit in February 2014 to concentrate on his role as the acting chief executive of the Far North District Council.
Mr Robertson said the work of commissioners finished on Thursday- a day after election results were officially finalised- but Mr Winder would work in his new role as the crown manager.
