Ireland back row Sean O’Brien believes Ireland can cause an upset when they take on New Zealand in their second summer test in Christchurch on Saturday morning.

Ireland were comprehensively beaten in the first game of the series, losing 42-10 last Saturday with Julian Savea claiming a hat-trick of tries in a stunning display.

However O’Brien is confident that the Christchurch game will be a different proposition.

“I think I’ve always said it, we need to get a consistency in our play. For a couple of phases last week we played some great stuff, put them under pressure and got a couple of penalties," he said on RTÉ’s Morning Ireland.

"We need to be doing that over a period of time in the game and really go after them instead of them coming after us.”

Saturday’s game will be the first time New Zealand play in Christchurch since February 2011’s devastating earthquake.

The game will take place at the renovated Rugby League Park, and while O’Brien is aware of the emotional significance of the encounter, he insists that Ireland will be looking for nothing less that a victory.

“There will be a lot of emotion involved in it. It’s the first game in the new stadium and we’re going to go down there and try to do a job on them. We’re not going down there to take the foot off because of the occasion,” he said.

“This team, the longer it spends together, the better it is. We’ve had an extra week together and had a look at the mistakes we made last week and hopefully we can nullify them and put in a good performance.”
