Warren Gatland’s squad travelled south on Monday ahead of kicking off their 10-match tour on Saturday at Toll Stadium in Whangarei.
Biggar is in the frame to feature against the Barbarians and could yet line up against Gatland’s son Bryn.
The Wales and Ospreys fly-half has been mixing with his team-mates on his first Lions tour.
He said: “There are a couple of characters in the squad, Ben Te’o and Kyle Sinckler. They are real good value off the field. Players like that are important when you are away from home for six weeks.
“Then there are the likes of me who keep themselves to themselves and let the bother guys take a bit of banter and stick. We have done a lot on the field, but also a lot off it with the lads sitting down at dinner tables, no one else from your country on there, and interacting.
“I made the decision when coming down to breakfast I did not want to be with players from my club or country because a tour like this is about getting on with guys you did not think you would get on with. You find out they are really good blokes and you get on well.
“That is really important and almost as useful as what we have done on the field. So far it has been good and no one has upset anyone.”
Biggar is one of three No 10 options in Gatland’s squad alongside England’s Owen Farrell and Ireland’s Johnny Sexton. All three are vociferous characters, and Biggar is enjoying the chance to work alongside two men he would normally see as rivals.
He added: “What I have found interesting with Johnny and Owen is the amount you pick up off them and and that goes for other players as well.
“We have chats after training and talk about tactics. The two have so much knowledge and it is really interesting. Johnny and I have got on really well and after playing so often against him, it is good to be on the same side. I am looking forward to challenging him and Owen and being with them gives you a good perspective on 10 play. We are not holding anything back from each other.
“The greater aim is to win the Test series so if any of us has any knowledge that can help the team win games from small detail, it is important we put it out there. We are all confident characters who are not afraid to speak our minds and say what we think. That will suit the team well.
“We are competing for the same position and we all want to play in that 10 shirt, but the most important thing is not the battle for places but we do everything on and off the field and back whoever is playing in all the games because we have the chance to achieve something historic.”
