 This criticism surfaced especially during a short-lived 2006 debate on further integration of the Auckland area, where many of the proposals included a proposed abolishment of the ARC, or a changed, less independent role.One of the mainstays of the ARC's work was expanding the parks network, which as of 2010 included 26 regional parks with more than 40,000 hectares, including many restored natural habitats and sanctuaries developed in co-operation with the Department of Conservation and volunteers.Of the rates collected by the ARC, 50% would go to fund public transport via ARTA, which is to amount to NZ$155 million in 2007/2008, up from $124 million in the preceding 2-year period 2006/2007.
