Rennie explained he wanted a young, up-and-coming hooker alongside former Samoan captain Mahonri Schwalger and he was not swayed by Harris having the higher ranking at NZ Under-20 level. "Whether he earned it is just one man's opinion," Rennie said.
"The [under] 20s coaches rated Nathan ahead of Rhys and we see it differently," he said. "From a selection point of view, we trawl through stats, watch the players play and view a lot of footage, we ask a lot of questions of other people if we don't know them so well, and find out about character. So we don't make any of those decisions lightly and we were pretty keen to get a young guy in ... and Rhys got the nod in the end.
"Nathan will be part of a group of young guys we are bringing in to training this week and for next week, so we will get a look at him.
"He didn't get to play a lot of ITM Cup himself, just a few games off the bench, so if he had that might have made a difference as we would have seen a lot more of him at that level," the coach of the Super rugby champions said.
