He is due back in Rotorua today, where he said he would get a haircut and have a shave, and then focus on his extramural sport science degree and becoming a fitness model.
The things he learnt would stay with him forever, he said.
"I have found I really am limitless. I have found the purpose to my life, and I know where I am going with my future."
Mr Paea said he never lost faith that he would finish, but some days were more of a challenge than others.
"The last three days were probably the toughest. I had had a lot of head wind and I was really tired. I was up in Gore when my bike got blown over, it was all uphill and I was going against the wind."
Beautiful scenery and speaking at schools were highlights of the trip.
"Going through Queenstown, past Lake Tekapo it was stunning. Mt Cook was in the background. I spoke at a few schools along the way and encouraged the kids to achieve their dreams."
