The former Kiwis and Warriors rugby league coach Daniel Anderson has guided St Helens to a 38-10 win against Leeds to reach a third successive English Super League Grand Final.
Leeds could still join them in the Old Trafford decider on October 4 by winning the final eliminator against either Wigan or Catalan Dragons.
It was the perfect result for Saints to pay tribute to club captain Paul Sculthorpe, the former Great Britain skipper who has announced his retirement.
Leeds coach, another former Kiwis mentor, Brian McClennan says the defending champions were shocked by their defeat.
