The “Tihei Wa Mauri Ora – emerging worlds” Gathering is a non-residential conference so people from out-of-Auckland will need to independently find their own accommodation.
Liston College is a west Auckland school and so is close to the western motorway (exit Lincoln Road). There is good public transport along Lincoln Road and to the transport centre (train/bus) in Henderson. There are a number of motels etc in the Henderson/Lincoln Road area.
