The Baby Blacks will be aiming for five consecutive International Rugby Board crown, and Penney said it was good to perform after a tough match against Wales.
"Really pleased, it was difficult circumstances last time we played Wales obviously and I was just really rapt that the boys had been able to grow over the last 10 days or so,” he said.
“I think technically they (the team) did a really good job and got the right outcome so it was great.
"Certainly that was a massive bonus for us getting those tries either side of half time, it really ripped the heart out of the Welsh. All in all a good day.
"I don’t think we are a side that is overly confident in what we are doing and that performance today I think will certainly give us a little bit of belief, which is important."
Co-captain Bryn Hall said they were expecting a tough fight from Wales.
"We always knew that Wales were going to come and fight, they are very, very passionate - just like New Zealand, very passionate on their rugby - so we knew that first 20 minutes were very important, trying to weather that storm,” he said.
“Those two tries just before and just after half time were very crucial for us. We talked about it a lot through the week saying that last 10 minutes and first 10 minutes after half time were very important.
Hall said the team learned the lessons from their historic defeat to the Welsh.
"For sure, it was very, very disappointing last time we played Wales though I guess we have learnt our lesson, we executed our game plan very well today, we played with a bit of width and we played much better with our kicking,” he said.
“The last time we played unfortunately we didn’t use that facet of play so we played much better today.
