Second-five Liv McGoverne has chalked up a hat-trick of tries to help Canterbury into their fourth consecutive Farah Palmer Cup final.
After scraping into the semi-finals on a countback over Northland and Counties Manukau, Auckland Storm had no answer to Canterbury's clinical display, as the southerners eventually ran out 36-21 winners.
Auckland led late in the first half, before Alana Bremner and Sam Curtis scored in quick succession to secure a 17-8 halftime advantage. Soon after the restart, McGoverne crossed for her second try to extend the lead and brought up her third in the 49th minute for 29-8.
The Storm rallied through tries to Theresa Fitzpatrick and Saphire Abrahams to close within eight points, but Cindy Nelles put the contest beyond doubt for the Cantabrians, who are seeking their fourth national women's title.
They will face the winners of Sunday's Waikato v Manawatū semi next weekend.
Canterbury 36 (McGoverne 3, Bremner, Curtis & Nelles tries; Cocksedge 3 conversions) Auckland 21 (Elliot, Fitzpatrick & Abrahams tries; Maliepo 2 conversions)
