Keeping players from the rising financial power of the north is the most challenging it's ever been, says New Zealand Rugby boss Steve Tew.
In an interview with Radio Sport's Daniel McHardy, Tew opened up on the increasingly "inevitable" prospect of All Blacks heading north and the concerning depletion of home-grown depth.
"There's no doubt the player market is as hot as it's ever been," said Tew. "The money coming out of Japan and France in particular is a bit concerning but there's no breaking news in that, is there?
"I think the money has increased in both those markets at least and there are some signs that it might heat up a bit in the UK too.
"At every level we're looking to retain the talent we want, from our sevens players right through to the top very experienced All Blacks.
