Bullock Creek or Punungairo[1] is a river valley in the Paparoa National Park, located just north of Punakaiki on the West Coast of New Zealand.
[2] Bullock Creek Road leaves State Highway 6 around 2 kilometres (1.2 mi) north of the visitor centre at Punakaiki.
It is a 6 kilometres (3.7 mi) long gravel road that provides access to the polje area and to the mid-point of the Inland Pack Track.
[6] Bullock Creek includes a rare and nationally significant polje, a large enclosed depression with steep sides and a flat floor, caused by subsidence in a karst region.
[7] Early settlers moved into the polje area in 1874 and began felling the forest and clearing native wetland vegetation to plant pasture for grazing.
The entire area is prone to inundation in heavy rainfall, as water from underground passages overflows and re-emerges at the surface.
The storm caused widespread damage and led to the closure of parts of the Inland Pack Track for two years.
In 2016, the section of the track between Fox River and Bullock Creek was re-opened after the clearance of around 400 fallen trees.
