Isitolo Maka left the Hutt Recreation Ground a frustrated man on Wednesday evening after watching his Tonga A side beaten 41-10 by the Hurricanes Development team.
It's Tonga's second straight Pacific Rugby Cup loss in New Zealand after the Chiefs development team put 50 points on them last week.
The Tongans made an industrious start and first-five Tomasi Palu probed the inside channels with some success but half chances were unable to be converted into points.
Isitolo Maka says unfortunately his players took a bit of a backward step.
"I think I'm a lot more disappointed with this game because I think everything went well but in our preparation - just a few mistakes that we made cost us a few more tries that shouldn't have scored. Games like this once you get an opportunity you've got to take it because, you know, they don't often come along. We didn't take our opportunities."
The results were much more encouraging for the other Pacific sides, with Samoa A pipped 22-21 by the Crusader Knights and Fiji Warriors holding the Chiefs to a 25-10 scoreline.
