Mr Pentecost would take over Chris Broadhurst's role after the long-standing principal called time on the position in June.
The new principal said he had been very fortunate to be offered leadership at a Bay school and was excited about what the future would hold.
"Good principal jobs do not come up that often, especially in the Bay of Plenty. It is an attractive place for people to want to live and work."
Mr Pentecost said it was a hard decision to leave Te Awamutu Primary School but was looking forward to the family's new adventure.
"It is like you have two families, your school life and home life," he said. "I am looking forward to the move and how I can continue my education leadership within the new school."
He was excited about the prospect of continuing his hobbies outside the classroom, which included waterskiing, wakeboarding, mountain biking and spending quality time outdoors with his children in the Bay.
"I am hoping to do a bit of fishing," he added.
Mr Pentecost intended to bring "open eyes and ears" to the school community at Omokoroa No.1 School.
"I am looking forward to building positive relationships with staff, parents and the children to keep that sustainability going. The rewarding aspect is being able to continue and foster that learning environment."
The father-of-three had taught all three of his children, aged 9, 13 and 15, in his 20-year career teaching at schools in Queenstown, Christchurch, Gisborne and Waikato.
Mr Pentecost had enjoyed working in semi-rural schools and said what he loved most about being a principal was being able to make a difference in children's lives.
"You are continuously at that level where you can make a change for a wide range of people and not just your own children," he said.
"I love seeing the smiles on the children's faces when they are loving what they are doing."
He had been working with outgoing principal Chris Broadhurst on the transition before he started his new role at the beginning of term one next year.
Mr Broadhurst said many people who applied for the job were of very high calibre.
"I think he [Mr Pentecost] would be great for the school and I am very confident he will move the school forward and have something we may be missing or consolidate what we do have."
