All Black Rieko Ioane 'burned' by Jacinda Ardern for his Bledisloe Cup try mistake

Prime Minister Jacinda Ardern imagines All Black Rieko Ioane was "schooled" during the halftime break at the Bledisloe Cup opener, after he dropped the ball attempting to score a try.

With New Zealand leading 8-3 over Australia just before halftime on Sunday, Ioane crossed the line for what would've been the All Blacks' second try, but as he went to ground the ball with one hand, he dropped it.

The try was awarded at first, but the video match official deemed Ioane had failed to control the ball while scoring. The game finished in a 16-16 draw.

When the Labour leader appeared on The Project on Monday, she was jokingly asked by guest host and former National cabinet minister Steven Joyce if she was going to enact "Rieko's law".

"People want to know whether you're actually going to pass a law, if you get re-elected, to stop one-handed try attempts," Joyce said. "We're going to call it Rieko's law.

"I feel like that's probably already part of the training," Ardern replied. "I just couldn't imagine the changing rooms in that halftime, I just thought he would be schooled.

"I really felt for him."

The Project co-host Kanoa Lloyd said Ioane's already had "a miserable 24 hours and he just got burned" by Ardern.

"Just never be complacent - that's the message," Ardern said.
