A former Hawke's Bay under-14, 16 and 18 rep, Walton-Sexton hopes to become a professional player in the near future.
"Whether it's for the Magpies or overseas, getting paid to play would be a good thing."
Walton-Sexton has several options for next year including a job offer on the Gold Coast and apprenticeships in the Bay.
The other five Bay players selected were the Napier Boys' High School trio of prop Jayden Walker, centre Leo Thompson and lock Tiaki Fabish and the Hastings Boys' High School pair of hooker Damarus Hokianga and midfield back Jordan Thompson-Dunn.
Former Te Aute College first five-eighth Raniera Peterson was also selected. A product of the Hawke's Bay Rugby Academy, Peterson, played club rugby for the Upper Hutt Rams this year.
The 25 players were identified through regional and national camps and selected on form from school, regional and club rugby. New Zealand Māori Board Chairwoman Dr Farah Palmer said it was an exciting programme for the team.
"This team and the programme that it is part of, embodies the principles of Poutamatanga and Taumatatanga that drive Māori Rugby.
"We are very proud of the large number of Māori players who have already been selected to attend the New Zealand Schools camp. Selecting talented Māori players in this team enables us to identify, develop and encourage our next generation of players to show their talent at this level within a Māori environment," Palmer added.
