Due to the challenges of the small marketplace, the brands that fly the domestic routes in New Zealand can change quite frequently. The national carrier, Air New Zealand has remained through it all however, and is still offers the most extensive network, serving most major towns across New Zealand.
Jetstar and Pacific Blue are currently the two main competitors, but mostly only on the busiest routes between Auckland, Wellington, and Christchurch.
The planes range from 737 jets down to medium size and tiny propeller aircraft. Most flights in New Zealand are short (under 90 minutes), so meals are not served, but on larger planes you usually receive a snack and a hot drink.
The main centres all have modern airports with good amenities, but some small towns may have very limited terminals. The usual airline security is conducted on the main routes, though not always on smaller planes. New Zealand security staff and generally fairly helpful and friendly, but that does not mean they are any less strict about what you can carry on an aircraft.
None of the airports currently have rail services to them, and shuttle buses or taxis are the best options for getting to the terminal.
There are also many other smaller scenic flight companies. These operate from the main tourist centres, and will also sometimes provide one way transport between two destinations. Auckland and Wellington are also served by small commuter airlines that operate to Hauraki Gulf islands and across Cook Strait respectively. Airlines also services Stewart Island (from Invercargill), and the Chatham Islands (‘Air Chathams’ from Auckland, Wellington, and Christchurch).
