"The rugby up here is pretty hardy," William says, "pretty much like it would be in Southland, I would imagine, the two tips of the country. The lifestyle itself is also pretty rugged and anything but flashy with boil-ups after training and such like. I think it will suit me really well."
William and Jack know they will have to fight for spots. "There are some really good players up here," Jack says, "but our aim is to start regularly".
The advantage in signing brothers is that they push each other in training like no one else can. "You don't want your brother to beat you at anything," Williams laughs, "and if they slacken off during training you certainly let them know".
Despite their progress, neither brother says they are thinking much about Super 15 selection yet.
"It's at the back of my mind but I am not getting ahead of myself," Jack says. "I haven't even made my ITM Cup debut."
And they say they won't have any trouble playing Auckland or North Harbour.
"If anything, you go harder when you play the place where you are from," William says.
The brothers are well over the attention that goes with being the sons of Auckland rugby royalty. "You learn to deal with it but it has been more of an issue with Dad's recent profile (as chairman of the Blues)," William says.
