Brunner, originally called Brunnerton, is a town in the northwest of New Zealand's South Island. It is 12 kilometres (7 mi) east of Greymouth, on the south bank of the Grey River. It is on the Midland Line railway near its junction with the Stillwater–Westport Line (SWL) in neighbouring Stillwater. Passenger trains ceased running along the SWL to Reefton and Westport in 1967, but the TranzAlpine runs the length of the Midland Line from Christchurch to Greymouth and it continues to stop in Brunner.
