Waratahs captain Dave Dennis credited his side's first half showing for their 25-20 win over the Chiefs in Sydney on Friday.
It was the Waratahs' fourth win of the season and pushed them to within eight points of Australian conference leaders the Brumbies, who play the Reds in Brisbane on Saturday.
"I thought we played really well in the first half, probably our best opening half of the season, but we slackened off a bit in the second half," Dennis said.
"It was great ticker to hang in there at the end to get the result."
Chiefs skipper Liam Messam echoed Dennis' sentiments and said his team had changed their approach after a poor opening half.
"It was a very disappointing first half for us, but I'm proud of the boys for the way they came back and had a great opportunity to win the game," he explained.
"We were going backwards a lot in the second half and we had to change our habits and I'm proud of the way we came back."
