As someone who played 10 tests for the All Blacks, Ireland scrum coach Greg Feek knows exactly what his charges can expect on Saturday.
Adding to the difficulties for his adopted side is the fact tighthead prop Mike Ross remains in doubt for the match at Eden Park due to a hamstring injury.
However, Feek, while acknowledging the All Blacks as World Cup champions and the forward pack as one of the best around, has urged his side to treat it as just another game.
"Everyone knows what they can do," 36-year-old Feek said of the All Blacks. "One of the first things is we just have to play our game and just treat it like you're playing any other country. It's not really anything different to what the boys have experienced in Europe but we respect the fact that obviously the All Blacks are the World Cup champions and we know it's going to be tough."
Feek's main job these days is with Irish club side Leinster, recently crowned European champions, and he plies his trade alongside fellow Kiwis Joe Schmidt, the head coach, and forwards coach Jono Gibbes.
