He said the crew returned to Whenuapai where the aircraft landed without incident.
"A local standby was called purely as a precaution and has now been stood down."
Earlier, Defence Force personnel at the base said the aircraft was on a flight from RNZAF Base Woodbourne, near Blenheim, and had suffered a "minor technical malfunction".
The aircraft was going through its precautionary landing procedure in such a situation.
Last October a RNZAF Boeing 757 carrying the Prime Minister and a trade mission to India had a malfunction at Whenuapai.
Last June a C-130 Hercules landed safely at Auckland's Whenuapai Airport after declaring a full emergency mid-flight.
