Rugby: All Blacks coach Ian Foster knows strongest team after test wins over Tonga, Fiji

All Blacks coach Ian Foster is confident he knows his first-choice XV, after his side's sweep of three tests against Tonga and Fiji.

In the lead-up to Saturday's second test against Fiji, assistant coach John Plumtree admitted certain positions were up for grabs for the upcoming Rugby Championship and Bledisloe Cup.

Debate had previously raged over positions such as first-five, where Richie Mo'unga and Beauden Barrett battled for the starting spot.

Elsewhere, players like Ethan Blackadder, Finlay Christie, George Bower, Quinn Tupaea, Ethan de Groot and Samisoni Taukei'aho have been given test debuts, as the All Blacks look to build squad depth.

But with three relatively straightforward test wins under their belts, the All Blacks are now clearer on what their first-choice team should be.

"I think so," he says. "The nice thing is [that] there's a lot of competition for places and that's the way an All Blacks squad should be. 

"Clearly, there'll be a lot of opinions about what the 'top 15' is. That's a great debate for everyone to have, but we've got a pretty clear idea. 

"The good thing is that we're really working on making sure the gap between our first-choice and second-choice is as small as possible, if there's even a gap. That's a positive that's emerged out of this month.”

Foster also allayed any fears over the fitness of winger Will Jordan, who came off after 43 minutes against Fiji, with what the All Blacks coach confirmed was a hamstring issue.

"Will looks like he's got a grade one [hamstring strain] - it's just a small twinge, so we pulled him off early.

"He's trying to convince the medicos that he's had this before and played the next week, but there's no game next week, so he can settle down and get over it.

"He should be fine for our camp the following week in Christchurch."

The All Blacks name their 36-man squad on Monday, building towards their first Bledisloe Cup test against the Wallabies on August 7.
