New Zealand and Australia are boosting their police numbers in Solomon Islands amid concerns that two attacks on Regional Assistance Mission, or RAMSI, personnel could be part of a conspiracy.
The New Zealand Foreign Minister, Phil Goff, says New Zealand is sending three investigators to help the inquiry into the murder of Australian police officer, Adam Dunning.
He says Australia will also send additional resources.
Mr Dunning was killed when shots were fired at his vehicle while he was on a night patrol in Honiara last December.
Earlier, shots had been fired at another vehicle belonging to RAMSI.
Four people are facing charges in connection with both incidents but Mr Goff says there is a fear others are involved.
"that there may be a conspiracy behind these attacks and it is really important to lessen the risk to other police officers by doing the investigation and bringing charges against all of those that we think may be complicit in the action, the attacks on the police officers."
