The 25-year-old got the visitors off and running with a try just before the break to cancel out an earlier effort from the dangerous Tim Visser, who scored a hat-trick, but a further two conversions and three penalties saw Penney's troops off to the perfect start.
"I thought Ian - without pre-empting anything - showed a great deal of maturity and that's what we are looking for from a young (number) ten," said former Canterbury head coach Penney.
"He is able to guide the team around the park and do the basics well. A lot of credit to the young man, he has shown a lot of fortitude and his perseverance is starting to pay off.
"We worked up some things during the week and I thought the boys played a lot of rugby, which was pleasing.
"We reduced the amount of unforced errors, which we had been guilty of in pre- season and I thought we defended with a massive amount of determination.
"I suppose the most pleasing aspect is that we leave here with a degree of confidence in what we are trying to do. The boys are pretty chuffed with themselves which is a great spur for them."
