Both sides struggled with the humidity which made the opening spell handling a challenge. Lock Sam Caird was New Zealand's go-to lineout man, but they could not always connect with him.
New Zealand's cause was helped greatly going into the final quarter when Australian tighthead prop Tyrel Lomax, son of former Kiwi John Lomax, was sinbinned for a dangerous neck roll on flanker Mitch Jacobson. Fidow's presence seemed to right the scrum, and New Zealand even poached a tighthead at the death.
The coaching staff and the players themselves will seek more on the weekend, but this was a solid platform from which to forge their world championship plans.
