In 2012, he was appointed chairman of the Iwi Education Authority for Nga Kura a Iwi o Aotearoa, representing Maori immersion schools.
Sir Toby said that over his time in education, the response to Maori learning had changed enormously.
When he trained, teachers were not taught any Maori songs, or any understanding of how Maori culture could influence learning.
"Today, that's all changed. In fact, many teachers are working hard to acquire the correct pronunciation of Maori names, working hard to become proficient in the language, and of course you have kura kaupapa, kohanga reo and waananga."
Sir Toby said being taught in te reo had a huge impact on Maori students' desire to learn and succeed.
"I see this every time I walk into the classroom," he said.
"There have been enormous changes, and some wonderful successes are occurring. However, in terms of across the board, we still have some way to go in achieving parity in all schools."
Sir Toby is also chairman of Te Arawa Lakes Trust, deputy chairman of Rotorua Te Arawa Lakes Strategy Group and deputy chairman of Te Waananga o Aotearoa Council.
He said his four children were "overawed by the acknowledgement".
