"It's been a good learning for the players and for us as coaches. We turned up in Munster on the back of a win in the US, and we weren't ready for the style of rugby, particularly given the conditions, we faced in Munster," he said.
Cooper said that the learnings from this tour will be important as the side look towards the 2017 British and Irish Lions series.
"Knowing that the Lions will probably play a similar style, it has been a good learning curve for us, and given us a good focus for our training this week.
"Players in Super Rugby in 2017 will have a great opportunity to play for a spot in the team, so that will be exciting to watch," Cooper said.
