The fire truck is the first of its kind in the country, it is complete with Māori artwork across the front and Te Rotoruanui ā-kahumatamomoe, Rotorua Fire Brigade, along the side.
Smith said he always knew "ahi" meant fire, but wanted to know more so recently took a 12-week te reo course.
"It proved very beneficial in the job. I've always thought it would be good to learn and I managed to learn some basic phrases."
He said one of the important aspects of te reo in the fire brigade was sharing safety messages with the community.
"It's absolutely important when we have so many kura in our community that are full immersion.
"We can send out firefighters who are fluent in te reo and deliver our fire safety messages and programmes to everything."
Senior firefighter Walton Lee is one of the instructors who works with those schools.
"We have started going out to kura and kohanga reo and we can use a language they really understand."
Lee said during his time as a firefighter the number of Māori within the brigade had grown.
