Captain Christie Yule ran a superb support line to score the Volcanix' first try in the 46th minute but the slick Auckland outfit hit back 10 minutes later.
Volcanix fullback Sapphire Tapsell plucked an intercept out of the air and scooted away for a try in the 70th minute to give her side hope. Auckland again forced turnovers to shut the Volcanix out, but not before 19-year-old Volcanix replacement back Nadia Flavell scored on fulltime.
