Dunedin has a great stadium, which i wish was here than the current Westpac one, but a prick to get to from the airport. They really need to sort their crap out down there with buses.
Anywhere in Dunedin is a prick to get to from the airport. Catch a shuttle into town, Forsyth Barr's location is very handy to Dunedin CBD and student district
Edit: but yes, the bus system is terrible!
