SIR Peter Jackson's personal Gulfstream jet is being used in the search for the missing Malaysian passenger jet, his spokesman has confirmed.
Radio New Zealand reported that Sir Peter had personally given the okay for the jet to be used in the search for MH370, which went missing on March 8 with 239 people aboard.
A list of participating countries and what resources they providing revealed a New Zealand military plane and a New Zealand civilian plane were taking part in the search.
The jet was not donated to help in the search effort, rather the company which operated the jet had accepted a charter offer with Sir Peter's permission, Radio New Zealand said.
The jet was being used to relay messages between different points, facilitating communication between others involved in the search.
A spokesman for Sir Peter today confirmed that the civilian aircraft involved in the search had been charted from Sir Peter.
He declined to say what remuneration was being offered for the charter or whether the jet was offered and was requested.
"Peter would not seek publicity for something like this and would actively avoid it in fact," spokesman Matt Dravitzki said.
"A lot of civilian and military aircraft are involved in the search and it's kind of disappointing that because one is owned by a celebrity it becomes a matter of news when there are [over] 200 people missing."
Sir Peter bought the jet last March for around $80 million. It is managed by charter service Execujet and is based in Wellington.
Gulfstream describes the G650 on its website as an "ultra-high-speed, ultra-long-range business jet" and as the "gold standard in business aviation".
"The flagship of the Gulfstream fleet flies faster, farther, and more comfortably than any other business aircraft in its class."
The jet can carry eight passengers and a crew of four on nonstop legs more than 12,000km.
