Thomson (28), who says he is "not getting any younger", is off contract at the end of the year with both the Otago and New Zealand unions, and has plenty of options to consider over where to play next year.
"To be honest, it is not something I've been really thinking hard about.
"I'm just concentrating on trying to do my best for the Highlanders and making it back into the All Blacks," Thomson said.
"But it will be hard to leave Otago. I've been here for eight or nine years now and played all my first-class rugby for Otago and the Highlanders.
"So I would not take a move away from here lightly."
Thomson has been rumoured to be in the eyes of the Crusaders, and did admit playing for a winning team was a bonus.
"Playing for a winning team helps, there is no doubt about that.
"It gives you confidence. And having good players around you, then your own game lifts, and your standards lift. Your mental state can be a lot better.
"But playing for the Highlanders you're still seeing a lot of action. So it can be lucky both ways."
Thomson said the All Black selectors were not too phased over what team you were playing for as they looked at individual skills and took into consideration who was around you.
Thomson has had to make adjustments this year as the new rule interpretations have meant one of his major strengths has been nullified.
Thomson was one of the best at turnovers last season - pilfering balls in the tackle, and earning penalties for his side as the attacking player becomes exposed.
But all that has changed, as now at the breakdown all the rights are with the attacker, and teams easily recycle the ball.
"The game has changed and the tackle turnovers have been lost. I guess there is nothing you can do about it.
"You just take your focus away from that and move it into other areas," Thomson said.
"One for me is to make more dominant tackles, rather than a tackle steal.
"Any time one of your main strengths is taken from you it is disappointing."
Thomson said he wanted to make more power tackles and get his hands on the ball more often.
He met All Black assistant coaches Steve Hansen and Wayne Smith yesterday, and said they too wanted to see more power in his game, and for him to increase his work in the air.
Thomson felt his own form was not too bad - a six or seven out of 10 - but there was always things he could do better.
He was more prominent on Saturday, getting his hands on the ball, as the side went down narrowly to the Hurricanes in an entertaining game at Carisbrook.
He was felled by Hurricanes winger Tamati Ellison with a fend to his eyes, and said his vision took a while to clear.
Though the side lost, it played better than previous weeks, as both sides scored five tries.
"We just wanted to get out there and enjoy ourselves.
"We were getting too worked up about what had gone on in the past.
"We just need to focus on what we can do in these last three games.
"There is plenty of time at the end of the season for reflection.
"We need to put in some good performances in the next three weeks."
