Top review options shift balance of power to Mangawhai The current KDC ward map. Each ward is currently represented by two councillors. A representation review in the Kaipara district could dramatically shake up the democratic landscape. The review could redefine Kaipara District Council (KDC) ward boundaries and shift the focus of power toward Mangawhai and Kaiwaka. The review seeks to address the current under representation of the Kaiwaka -Mangawhai ward in favour of the Dargaville ward. The review has also been triggered by the need to implement a new Maori ward. Election Services general manager Dale Ofsoske made a presentation to KDC this month outlining different possible options for the new democratic format.
