Operators accept NZ electricity bills (Genesis, Mercury, Contact, Meridian, Frank, Powershop, Electric Kiwi, Octopus NZ), gas bills (Genesis, Contact, Vector), broadband bills (Spark, Vodafone NZ, 2degrees, Orcon, Now, Slingshot), local council rate notices (Auckland Council, Wellington City, Christchurch City, etc.), and bank statements - all dated within the last 3 months. Mobile phone bills are sometimes rejected. Water bills are not common in NZ outside Auckland (most areas have water charges bundled with council rates) so this proof-of-address category is rarely used. Body corporate (apartment) statements are accepted in most cases.
