Labour's plans for a feel-good announcement in the lead up to the All Blacks Samoa rugby game were gazumped by Prime Minister, who revealed it for them at his weekly press conference.
Mr Key will fly to Samoa with a number of other MPs, including Labour leader Andrew Little, to watch the game.
Mr Key was asked about reports that the Air Force plane would be taking rugby balls over.
Mr Key said he was reluctant to steal Labour's thunder but revealed the balls in question were rejected because of a spelling mistake.
He said Labour had instead arranged to take the unwanted balls to Samoa on the Air Force Boeing.
