Neems, who opened the scoring for Claudelands, latched onto a Ryan cross to tap home from close range. Pāpāmoa struck back minutes later after a defensive break down from Claudelands allowed open space for the away side to break through and score the equaliser.
Ryan put Claudelands back ahead thanks to a spectacular volley from just outside the box before half time.
In the second half the game became a more scrappy affair, with the game stopping and starting due to the officials.
Pāpāmoa equalised early on in the second half before Rachel Porteous scored the all-important penalty to give Claudelands the win, and unknown to them at the time, the WaiBOP W-League title.
The celebrations will be short lived, as all eyes must now turn to the main goal of returning to the Northern League.
They will face either Hibiscus Coast or Ellerslie AFC in early September in a home and away leg for a chance to be among the best in the region once again.
