Winger Zac Guildford is confident the All Blacks can ratchet up their attack when they take a 1-0 lead into the second rugby Test against Ireland in Christchurch on Saturday.

New Zealand showed plenty of fizz despite limited preparation in running in five tries in a 42-10 win over the tourists in Auckland on Saturday in the opening match of the three-Test series.

“We hardly touched on our attack during the week,” Guildford said of the build-up to the Eden Park encounter.

“We relied on our individual flair and how we’ve been going for our franchises, so once we get into our team patterns and work on things, I think we can build a lot more.”

Normally a left winger, Guildford operated on the right in what was his ninth Test to accommodate debutant Julian Savea, who cashed in with a hat-trick.

Guildford is multiple try-scorer himself, getting four against Canada in a Rugby World Cup pool fixture last October.

While he showed his usual industry on Saturday night, the 22-year-old Crusader found most of the play heading to the opposite flank, although he was philosophical about that.

“That’s the way it goes,” he said.

He was also aware that the competition for places in the backline meant players were on notice to perform to hold their spots.

“On our Thursday training, we ran two teams against each other and it was pretty much like an All Black trial,” he said.

“It’s a lot of fun when you’ve got that competition to keep you on your toes.”

Guildford described the atmosphere within the All Blacks camp as a relaxed one, and attributed part of that to New Zealand finally landing the World Cup again after a 24-year wait.

“Putting the World Cup behind us and winning that was pretty big,” he said.

“You’ve also got some new talent coming through and everyone seems to get on really well.”
