The Solomon Islands high court registrar, David Chetwynd, says the inquiry into the death of New Zealand diplomat, Bridget Nichols, will be held in the high court building in Honiara because the supply of electricity there is reliable.
Many parts of Honiara suffer intermittent power cuts.
The inquiry will open on June the 13th and follows a preliminary police finding that Ms Nichols' stabbing death in March was the result of an accident.
Mr Chetwynd says he is yet to get all the papers from the New Zealand detectives to be presented at the hearing.
It is not clear what New Zealand officials will be attending the inquiry.
