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.
Central Auckland is easy to navigate, and due to its compact size quite possible to do on foot. Greater Auckland is a different matter, as the city covers an area comparable to London, without a particularly effective public transport system.
There is a suburban rail system that has been steadily improving in recent years. Buses are plentiful.
Intercity Coachlines  operate a national bus network with many departure and arrives in to Auckland every day of the year. Tickets can be purchased online or throughout the country at numerous agents including the i-site network. A cheaper 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.
