Poor conditions have caused police to suspend the search for a man missing on a Southland lake for the rest of the day.
Police said the water level was still high and the weather outlook was not good and was expected to hinder their search.
"Conditions will be continually reassessed to determine further search activity."
Police ask that anyone in the area who locates any debris to record its location via GIS, if you have the capability, as well as photograph it, and get in touch with police.
These items can then be checked by the search team once weather improves.
Earlier, Invercargill police said it believed the missing man and the woman he was with got into difficulty nearly a week before they were reported missing.
Their four-metre boat was reported missing on Lake Hauroko on Friday.
A woman's body with a life jacket nearby were found at the lake on Saturday along with items from the boat including camping items and food.
Sergeant Ian Martin said the pair from Christchurch who were in their 60s, had headed out for a camping trip to Caroline Hut - halfway around the lake - a week earlier, on 26 May.
"We're reasonably certain that they went on to the lake on Sunday and we have spoken to some people who happened to be there when they launched the boat.
"They said that the conditions on the lake were actually quite good at the time."
Sergeant Martin said their names were not in the Caroline Hut visitors' book.
"We've checked all the huts on Lake Hauroko and nothing's been left there."
It appeared they were missing for some time before the alarm was raised, he said.
It was extremely cold on Saturday when searchers recovered the woman's body, and conditions had not been particularly good since then. The lake had risen 400mm since Sunday.
He said Maritime New Zealand would join the investigation tomorrow, and the police national dive squad may be used when the water level had dropped.
They were still hopeful of finding the man, even though the lake was the deepest in New Zealand.
"There is a reasonable area to search before it drops off into the deep part."
