Ms Douglas, who is the principal of Te Kura Kaupapa Maori o Otepou, says te reo is vital to her life and has instilled that importance into her family.
She only started learning Maori language in her first year at high school but continued to learn through tertiary studies, Te Ataarangi courses and other programmes available to her.
"Whatever way I could improve my reo I did it," Ms Douglas said.
Ms Douglas said her career in education was prompted by her desire to ensure her children learned te reo. Her four children are all fluent and it is the first language of her three grandchildren.
"I really wanted to be involved in my children's learning and ensure they had quality Maori teachers," she said.
"It's just really important that they have their native tongue."
Ms Douglas said acknowledging te reo during Maori language Week was a good start towards putting more emphasis on the importance of the language in New Zealand and hopefully recognising it as an official second language of the country.
"To truly be bi-cultural, we need to be bilingual."
