The southern franchise beat the Crusaders last Saturday night and, with the Rebels losing, the Highlanders are now the only side to have won all their games so far in the competition.
Highlanders assistant coach Glenn Delaney said the side was not getting carried away with its start.
''We are just focusing on doing what is front of us and getting all the little things in our game right. The outcomes are sort of taken care of themselves,'' he said.
''But the detail that is going in and the work that is going in - it is coming out pretty well.
The side though has played all its games under the roof at Forsyth Barr Stadium so far - winning all three - but will venture north this week, taking on the Hurricanes in Wellington on Saturday night.
''It is brilliant, isn't it? Every time you wake up the day after game day there is a challenge on the horizon. The Hurricanes in Wellington going to be an epic challenge.
''They have got threats across the park and they defend aggressively so we can't wait to be involved.''
Delaney looks after the defence for the side and said overall he was pretty happy with the way it has played out so far this season.
''It is getting there. On the grumpy side of the ball, am I ever happy? I don't know. Some would say no. There are some really challenging pictures coming. The Crusaders put some really challenging pictures in front of us. Sometimes we dealt with them and sometimes we scrambled well.
''At the moment we are trending a couple of tries a game which is not too bad. I would like to pull it back if we can but the change of the laws in the breakdown. So defensively we have to come in from our own side whereas the tackler used to be able to come back in from the other side of the ball.
''Not being able to do that means it is pretty difficult to slow the ball down.''
He had no issue with players standing in front of the ball carriers acting as dummy runners.
''What we would do is bring it back to what we can control.''
Delaney said the Highlanders were not getting too caught up in what Ben Smith did or did not do in his conversation with referee Nick Briant last Saturday night.
Smith talked to referee Briant after Crusaders No8 Jordan Taufua scored a try just before halftime. The try was eventually ruled out after Briant sought a ruling from the television match official.
''Players and referees, and captains particularly, have the right to have communication. They always do. There is a lot of respect and empathy there and we will follow the guidelines whatever Sanzaar puts down. But it is an integral part of our game.
''It is not something we are particularly stuck on. We will just move on.''
Delaney said there were no injury concerns for the side apart from flanker Liam Squire who broke his thumb last Saturday night and would be out for six weeks.
