The Chiefs went to the top of the Super Rugby standings after they beat the Hurricanes 12-17 in Wellington.
Weather conditions prevented the match from being a free flowing clash which was decided by a single Chiefs try.
The result provisionally moved the Chiefs to the top of the Super Rugby standings but they could be overtaken by the Brumbies on Saturday if they beat the Waratahs in Sydney.
Regardless of what happens in Sydney the Chiefs will remain the leaders of the New Zealand Super Rugby conference for the week as they now have a seven point lead on the Blues.
Rival flyhalves Aaron Cruden and Beauden Barrett - both All Blacks last season - engaged in a goalkicking duel throughout the first half of a match played in wet and slippery conditions in front of the 12,998 strong crowd.
Cruden kicked four goals from five attemps and Barrett three from three as the Hamilton-based Chiefs took a 12-9 lead to halftime.
Tanerau Latimer's try in the 54th minute clinched the Chiefs' ninth win from 12 matches this season, though they played the last 10 minutes with 14 men after replacement prop Ben Tameifuna was sin-binned for a professional foul.
The first half was a tough, physical contest in which both teams used strong-running forwards and kicks both in the air and along the ground to test opposing defenses.
But the match followed the trend of recent games in the New Zealand conference and deteriorated sharply after halftime as neither side managed to hold possession for an extended period.
After kicking his first four goals in succession, Cruden missed his next three which included a penalty attempt from more than 50 meters on halftime and the conversion of Latimer's try.
Latimer started as a replacement for openside flanker Sam Cane who was ruled out of the match with a back strain.
Barrett landed his first three attempts at goal in a tit-for-tat battle with Cruden through the first half.
He raised the flags in the third, 16th and 32nd minutes, while Cruden was successful in the fifth and 10th minutes - giving the Chiefs their first lead of the match - and in the 19th and 35th, the last giving them their narrow lead at halftime.
Barrett then didn't have another opportunity until the 69th minute when he landed a penalty from the infringement for which Tameifuna was sin-binned.
That cut the lead to five points but, though down to 14 men, the Chiefs defended stoutly for the remainder of the match.
They were helped by the fact that, with the prop Tameifuna off the field, the match reverted to golden oldies scrums and that prevented the Hurricanes applying pressure and forcing turnovers at the set piece.
Friday's win was the Chiefs' first in Wellington since 2001.
"For me personally and a few of the lads it was our first away win on this ground," Chiefs captain Craig Clarke said.
"So that means a fair bit. We talked about it.
"But any game against the Hurricanes is a tough battle and a tough local derby and the conditions added to that."
