A local government specialist says Auckland super-city ratepayers will see major changes to their rates bills, with some likely to rise by up to 20%.
Parliament on Thursday passed a law that merges eight councils into one, which also means standardising the way rates are set.
The local government centre director of Auckland University of Technology, Peter McKinlay, says there will be a major shift in charges, with some rates going up by between 10% and 20%, but others will go down.
He says the way rates are set now varies from council to council, with some using a property's assumed rental value, some using capital value, and some using land value.
The council merger takes effect next year.
