After Southland's withdrawal, the impressed Gaze felt WHS was the next best team to fill the spot in the national tournament.
"The school, the boys and parents are over the moon," said Malcolm.
"We've played and beaten some top schools this year but this is another level schools like St Kentigern, Hamilton Boys etc so a big ask.
"It's a pinnacle of their season and it just highlights all the work they've put in. You don't see schools like Wanganui High School at these things."
New Zealand sevens coach Gordon Tietjens uses the Condor Sevens to discover future stars, and will select six players to attend a training session with his New Zealand team after the tournament.
It will be an excellent end to the year for the Wanganui players who were members of the school's First XV.
Six of them will be heading to Massey University next year and Malcolm is currently hunting for any local employers who can take them on for summer jobs.
The Condor Sevens will be December 2 at Kelston Boys High School.
