Touzel was pleased with Collegiate's defensive work against bigger opposition and said the set piece - barring the line-out - was fantastic.
"For most of the first half they had the majority of the ball but we defended really well," Touzel said.
"But then [NPBHS] bring on the bench and they replace big with bigger. Physically it was always going to be testing for our guys. They just wore us down. We realise that was always going to happen."
Touzel hoped Tuesday's effort against one of the stronger sides in the country boded well for the season.
Collegiate's next outing is against St Peter's Cambridge in the first Central North Island 1st XV competition match next week.
Meanwhile, Collegiate's hockey side went down 7-0 to NPBHS. Touzel said Collegiate had a "very talented" but young side and the match would have been good experience for them.
The 1st XI football side went down 8-1 in what Touzel said was a tough ask for the visitors.
"New Plymouth is a very good soccer side. They were superb."
