The Chiefs trip to Argentina during the upcoming Super 15 break is off.
The defending Super 15 champions were set to face a second string Pumas side in Buenos Aires as part of a 10 day trip funded by the Argentinean Rugby Union.
The game was announced in December last year.
However, Chiefs coach Dave Rennie has confirmed that the sponsor has fallen through and the tour has been cancelled.
"Unfortunately we had some issues around the Argentina Rugby Union. The sponsor they had sorted has fallen through, so we're not going.''
