The Crusaders have extended their unbeaten Super Rugby winning streak to 12 matches, a storming second half setting up a 31-24 win over the Chiefs in Suva.
Friday's win was built around an uncompromising forward effort, slick handling and the ever-reliable boot of five-eighth Richie Mo'unga.
The New Zealand conference leaders ran in three tries to the Chiefs' four, with Mo'unga adding four penalties and two conversions in a crucial 16-point contribution.
The Crusaders were hit by the late withdrawal of flanker Matt Todd, still recovering from a head knock in last week's bruising 20-12 win over the Hurricanes.
In his absence, Pete Samu switched to the openside and Heiden Bedwell-Curtis pulled on the No.7 jersey.
