1938 Kopuawhara flood

On 19 February a flash flood swept away a Public Works railway construction camp at Kopuawhara on the East Coast, killing 21 workers.

 

Twenty men and one woman were drowned when a sudden cloudburst sent a wall of water surging through a public works camp at Kopuawhara, near Mahia. This was New Zealand's deadliest 20th-century flood.

Located on the banks of the Kopuawhara Stream, the No. 4 camp had been established for workers building the Wairoa–Gisborne railway. Houses for married men were situated up on higher ground, with a cookhouse and huts for 47 single men closer to the river bank.

While the stream was in flood due to heavy rain, the level had been higher at other times and there was no sense of danger. No one was prepared for the 5-metre-high wall of water that hit the camp sometime after 3 a.m.

One worker woke just as the water breached the banks of the stream and began pouring across the camp site. He tried in vain to raise the alarm, running from hut to hut and frantically beating on the doors before being swept away. Men struggled in water up to their necks. Some took refuge on the roofs of their huts, but the torrent collapsed most of these structures.

Other workers climbed onto the roof of the cookhouse. This structure partially collapsed, but they managed to hang on and were rescued when daylight came. The 11 men who took refuge in one of the work trucks were not so lucky. The force of the water tossed it onto its side, sweeping its occupants away; remnants of the vehicle were found 12 kilometres downstream.
