"That's no excuse and in fact, individually, the boys played pretty well. We were just guilty of leaking a few goals," Atkinson said.
"To be fair, the quality of teams we were playing was right up there."
Atkinson said the four named in the wider Central Hockey League Under-18 squad to play at the nationals next month - Lee Moir, Joseph Redpath, Ryan Gray and Ben Pilet - played well, although the return of his sons Martin and Reid helped Wanganui stay in touch.
Martin Atkinson is now based in Auckland and the 2013 Junior Black Sticks wider squad member was recently named in Sport NZ's latest Pathway to Podium (P2P) programme, designed to help young athletes reach the elite level.
"To be fair, Martin was probably head and shoulders above the others, but you would expect that with the accolades he has been given."
Mark Lyes, who co-coached the women with Jan Dixon, said he was happy with the team's performance.
"Definitely, the girls played well and those two sides that finished ahead of us were full of age group regional and national representative players. There were only two goals in it against eventual winners Horowhenua and we had our chances to score," Lyes said.
Lyes singled out goalkeeper Emelia Stanley, Sarah Reid and Emma Rainey, who has been named in the CHL Under-18 side to play at the nationals, for special mention.
