Fiji police say hopes are fading of finding the bodies of three teenage sisters believed to have been dumped at sea by a man who confessed to killing them near Rakiraki.
The police commissioner, Andrew Hughes, says a large fishing vessel is being chartered today with a powerful depth sounder in a bid to speed up the search.
Mr Hughes says that while the area divers are searching in is only 6 metres deep, the bottom is muddy and the weather has been rough, making visibility very poor.
"Hope is fading I have to say, it's been now about 11 days since the girls disappeared and the area does have strong currents but we are determined to do all we can to recover the girls or further evidence of what he claims to have done."
Mr Hughes says 70 police and a similar number of volunteers are involved in the search.
