Christchurch's international airport is the South Island's main hub. Air New Zealand flies here from 15 domestic destinations, while Jetstar has flights from Auckland and Wellington. Air New Zealand also flies between Timaru and Wellington.
Christchurch is the hub for coaches and shuttles heading up the coast as far as Picton, down the coast to Dunedin (and on to Te Anau), over the Alps to Greymouth and inland down to Queenstown.
The TranzAlpine service connects Christchurch and Greymouth, and the Coastal Pacific chugs north to Picton, with ferry connections across Cook Strait to the North Island.
