The search continues for a diver missing off Canterbury's Banks Peninsula.
Seddon Ralph Jane, 42, of Wairoa, was reported missing and a search was launched about 10am on Saturday.
He is assumed drowned after a five-hour search failed to find any sign of him on Saturday, but the National Police Dive Squad continued the search on Sunday morning.
Jane was expected to surface near Akaroa at 9.45am on Saturday, but failed to show up.
Searchers, including Coastguard volunteers, used a helicopter and up to eight boats to scour the area between Damons Bay and Flea Bay over the following five hours, but failed to find him.
In a statement, police said their dive squad would start the "recovery phase" of the search for the missing diver on Sunday morning.
Police and search and rescue continued making enquiries on Saturday evening to narrow down the search area.
Reception in the search area was hindering communication for Police on Sunday morning.
"Police's thoughts are with the man's family at this time," they said.
Coastguard southern region manager Cheryl Moffat said a rescue boat from Lyttelton had been involved in the search on Saturday, as no Coastguard unit was based at Akaroa.
Coastguard crews from Sumner and Waimakariri had been covering Lyttelton Harbour on Saturday as fine weather and the long weekend brought more people onto the water.
Volunteers had assisted with several boat break-downs, but no serious incidents had been reported in the harbour, Moffat said.
Akaroa residents said conditions were lovely on Saturday and "could not have been a been a nicer morning".
"Variable wind and not much of a roll, pretty much flat."
