Injury has forced the Kiwis into a late change for the Samoa clash on Saturday, which may force them into several positional changes.
Melbourne Storm second rower Kenny Bromwich picked up a groin niggle at training on Thursday afternoon, and has been ruled out of the World Cup opener.
He's been replaced in the 17 by Rooster prop Jared Waerea-Hargreaves, who will play his 20th test for the Kiwis.
But the situation leaves the Kiwis coaches with a quandary, as Waerea-Hargreaves probably won't be able to play in the back row.
He started his career there, but has been in the front row for most of this decade.
