The Chiefs held on to beat the Western Force 22-21 to extend their winning streak over the West Australian franchise to four matches.
The Force outscored the Super Rugby champion Chiefs by two tries to one and the hosts had to rely on Aaron Cruden's boot.
Cruden was flawless in his kicking as he kicked five penalties and a conversion while Jayden Hayward of the Force kicked three penalties and a conversion.
In total All Blacks flyhalf Aaron Cruden kicked 17 points during an unexpected starting appearance for the Chiefs.
Cruden was originally named on the replacements bench in order to get some rest but was promoted into the starting lineup when fullback and regular goalkicker Gareth Anscombe broke his toe in training.
Winger Pat Dellit scored a try in each half for the Perth-based Force.
The Chiefs led 22-11 immediately after halftime but the Force enjoyed the better of a scrappy second half, closing within a point when flyhalf Jayden Hayward converted Dellit's second try in the 61st minute.
The Chiefs had seemed in control of the match in the first half, scoring a try through Lelia Masaga and leading 19-11 at halftime.
But they lost all momentum in the second half, couldn't reach the gain line, began to slip off tackles and were lucky to save the match against the Force, who finished with only 14 men.
The Force conceded long strings of defensive penalties in both halves and tighthead prop Kieran Longbottom was sin-binned in the 71st for deliberately collapsing a scrum, though it seemed he had lost his footing on a wet and sub-standard playing surface.
The wet conditions confounded attempts from both sides to play fluent, attacking rugby.
Dellit's tries for the Force were well taken and Masaga scored after a steady buildup by the Chiefs but both sides made too many handling errors to make the match entertaining.
The Force may have been fortunate to have been awarded their first try to Dellit in the third minute from what seemed a forward pass.
But they were unlucky to be as heavily penalized as they were for the remainder of the first half when it seemed the Chiefs also infringed frequently at breakdowns.
The Force played more assertively in the second half and, after Cruden had kicked the last points for the Chiefs in the 44th minute, threatened to snatch the match with Dellit's second try.
