A Shaun Johnson 40/20 sparked a revival and, after Jason Nightingale inexplicably bombed a try, Proctor showed great strength to wrestle through three defenders and score. The Kiwis dominated the rest of the first spell and should have had more to show for their efforts. After Greg Inglis powered over from dummy-half to restore Australia's lead in the 21st minute - somewhat against the run of play - New Zealand had numerous chances of their own.
They took one, with Lewis Brown slipping over from close range. Brown spent three years in the international wilderness and scored a try with his first run.
After several opportunities, Johnson took the Kiwis into the lead for the first time shortly after a bullocking 50m run by Greg Eastwood.
Johnson evoked memories of Allan Langer's deeds on this ground, as he chipped and regathered, before stepping Dylan Walker to score.
Four minutes later there was more. Dean Whare leaped superbly to take a Foran kick.
Finally - to ease the nerves of long-suffering Kiwis fans still biting their nails - Jason Nightingale scored to seal the result with 12 minutes to play.
Kangaroos: 12; Kiwis: 30 (K. Proctor, L. Brown, S. Johnson, D. Whare, J. Nightingale tries; S. Johnson 5 goals). HT: 12-12
