"It's good for Tauranga, it's good for me and it's good for New Zealand First," he said.
"The top 10 is certainly a very strong team and I look forward to working alongside them."
NZ First leader Rt Hon Winston Peters said Mr Mitchell was a talented candidate who had already demonstrated serious commitment to Tauranga.
"Tauranga, and the Bay of Plenty, is very important to New Zealand First because we started there 21 years ago."
NZ First's deputy leader Tracey Martin was ranked in second place after Mr Peters, followed by list MP Richard Prosser third, Rotorua candidate Fletcher Tabuteau in fourth and list MP Barbara Stewart in fifth, before Mr Mitchell.
NZ First won a 6.59 per cent final share of the party vote in the 2011 General Election, good enough to claim eight list MP seats in Parliament.
