Assistant coach Ian Foster believes the All Blacks will face a stern challenge in pool play at the 2019 Rugby World Cup in Japan.
New Zealand's in Pool B along with traditional foes South Africa, Six Nations strugglers Italy, an African qualifier and a repechage winner.
Foster remains wary of South Africa even if the Springboks are struggling at the moment.
South Africa lost eight test matches last year including heavy defeats by the All Blacks but Foster told Radio Sport Breakfast in World Cup years they will be able to pick players from all over the world.
"If that comes to fruition then clearly they're going to be a different beast in the World Cup year than what they are now."
Foster told Radio Sport Breakfast it's a testing pool.
"We've obviously got a really big game in South Africa and that's going to give a really good edge to things and I think that's important in that pool.
"Italy, even though we've had a good edge over them for a long time, I think they're an improving team."
After failing to get out of pool play in 2015 England face another battle to get out of its pool at the 2019 World Cup in Japan.
The pool of death is C with England, France and Argentina grouped together.
Foster told the Radio Sport Breakfast there are plenty of talking points.
"Particularly that England, France, Argentina pool will be a bit of fun, but the fact that we've got a really big game in it is going to guarantee an edge for us. Now we can put it away and focus on the Lions."
The winner of the All Blacks pool will face the runner up in Pool A that includes Ireland, Scotland and Japan.
The All Blacks could face England in the semi finals if both sides win their pools and quarter finals.
