The person was travelling in a car with two others south of Ōpōtiki when the vehicle they were in went down the bank between Waioeka Pa Rd and Waiata Rd, about 10.20am on Friday.
“We haven’t found the car or person yet, [the search is] still ongoing,” said Mark Looney, owner-operator of Motu River Jet Boat Tours in Ōpōtiki.
“When water conditions improve [the] national dive squad will arrive,” he said.
Since Friday teams had been searching from the crash site “right down to the sea”, Looney said.
