Several stars also emerged from the team.
Te Rangitira Waitokia starred in the Wanganui and New Zealand Heartland back lines. In fact, he was an integral part of the Wanganui team that won the Meads Cup.
Hare Meihana is another to take the eye of astute judges.
Meihana played in the Wanganui U20 team that competed in the Hurricanes development series and was voted player of the tournament.
Malcolm said he understood upwards of 90 percent of last season's players would return this year and he was excited about that.
"We will lose one or two like Te (Waitokia), but 90 percent are coming back and we have 100 percent backing again from the St Johns Club," Malcolm said.
"While they call the Colts grade U21, it's actually open to U23 with weight restrictions. What we are especially pleased about is those players who had last season cut short through injury are also coming back.
"There was a lot of raw talent among those injured players and some of them could quite easily have followed a similar path to Te with further development and that's just what we plan to give them this year. I hope the union puts together a plan to attract any school leavers to this concept.
