A New Zealand detective has returned to Solomon Islands as part of the investigation into the death of the diplomat Bridgett Nichols.
Mr Pearce is in Honiara to seek legal advice from the Director of Public Prosecutions Office about a preliminary inquiry into the stabbing.
But the New Zealand officer has not brought with him a forensic report as expected by Solomons police.
He says the results are still not available.
After talks with Mr Pearce, the Solomons Criminal Investigation Department now believes the New Zealand police have a suspect for the killing.
Bridget Nichols, who was 50 and New Zealand's deputy High Commissioner, was fatally stabbed in the grounds of her residence two months ago.
