The Auckland Region is in the North Island of New Zealand. Centred on the Auckland metropolitan area, the region includes ruggedly beautiful west coast beaches and harbors, the more sheltered inlets and beaches of the east coast, the islands of the Hauraki Gulf and the hiking trails of the native bush-clad Waitakere and Hunua ranges.
See the Auckland guide for information on accessing the region by plane.
There is a suburban rail system and buses are plentiful.
InterCity  operates a national bus network with daily services to and from Auckland from around the North Island. Tickets can be purchased online, over the phone or in person at numerous agents around New Zealand, including the i-SITE visitor network. Another option is nakedbus.com  which also has daily services across the country, including to/from Auckland Airport. Fares start at $1 if you book early enough.
