"National office had identified them as too much of an accident risk," he said.
It was therefore decided as stations were upgraded, they would be rebuilt or redesigned without the poles.
Callister himself can testify to the harm pole-sliding can cause.
"I've hurt myself a few times.
"The [Pitt St] station's fireman's pole is three storeys high.
"If you let go at 3 storeys then you're at risk of serious injury... basically you come down and you don't stand up."
Callister said fireman's pole sliding also required some forward thinking. To do so without injury you needed long sleeves and the correct type of footwear.
One of the last remaining poles within the Pitt St fire station was used sporadically. Callister said there was one other pole remaining in the Auckland region - he wasn't sure about the rest of the country.
Callister said he had memories of sliding down the poles as a young firefighter.
They were a "legacy of history" he said that was had been described in picture books and movies throughout history.
The move to phase out the poles mirrored a similar move implemented in American fire stations. Several stations in the US are said to have incorporated slides into their design as a replacement.
But for now, Callister said Kiwi firefighters were sticking to the stairs.
"And when we're taking the stairs, we're told to walk."
