"I've always been interested in economic and social issues."
Mr Newman, who manages McLeod's Booksellers, said he was interested in getting things done, which was part of the appeal of being involved in politics.
He said the role wasn't a paid position, and people would still need to see an MP for electorate issues.
However, for political concerns they could get in touch with him. Mr Newman said he was looking forward to getting stuck in to his role "all guns blazing".
He said it was "inappropriate" to comment as to whether he would be running to be the Labour candidate for Rotorua in the next election and said the role wasn't an automatic stepping stone to the candidacy.
