Beauden Barrett slotted a drop goal shortly after moving into flyhalf to spark a final-quarter resurgence by the Blues that carried them to a 24-12 win over the Chiefs on Saturday.
Barrett, who started the game at fullback, replaced No.10 Otere Black with about 20 minutes remaining and put over the drop goal four minutes later to give his side a 16-12 lead.
He then added a 69th-minute penalty and winger Mark Telea finished off the best movement of the match three minutes after that to cap the 11-point burst that gave the Blues enough room to clinch victory.
The Blues had not won in Hamilton since 2011 and have now won their last six games, including a 30-20 victory over the Hurricanes in their first game of the new competition last week.
Chiefs - Penalties: D. McKenzie (4).
Blues - Tries: Hoskins Sotutu and Mark Telea; Conversion: Otere Black; Penalties: Black (2) and Beauden Barrett; Drop goal: Barrett.
