"This presents a great opportunity for others to step up and be a part of our plans going forward for the rest of the year.
"Sam has been a part of our squad for a long time now and when he's called upon, I know he'll step up," Hudson said.
"I have said for a while now that I believe Alex Rufer is one of the best young players in New Zealand and it's an opportunity for him to show his ability in two very big games."
Hudson said the All Whites, who began arriving in Auckland on Sunday, were looking forward to playing at home in front of a good crowd at QBE Stadium on Friday.
"We only have our full squad together for two-and-a-half days before kick-off, so every minute with the team counts."
