Fire risk management nation adviser Todd O'Donoghue said it was, however, important to look at the "whole picture".
"It's about the total cost more than just numbers. By this time last year we'd had three or four houses that had burned to the ground."
So far this year, the blazes hadn't been as serious and most of yesterday's callouts were minor, Mr O'Donoghue said.
"However, there are half a dozen incidents of interest. They did include damage to wharves, one in Wellington and one in Auckland, as well as damage to a desk at a Hamilton school. Also in Hamilton there was an event where a fire in the roof of two adjoining houses did damage to both of those properties."
The 58 figure includes three incidents where the cause of the blaze is yet to be finally determined.
They are fires at Upper Hut College's technical block last night, a shed in New Plymouth and a house north of Auckland.
A northern fire spokesman said there were 26 firework-related callouts in the northern part of the North Island overnight, including a blaze in trees in the Auckland suburb of Stillwater that took almost three hours to put out this morning.
Mr O'Donoghue said the Fire Service's most important safety manage for people letting off crackers tonight was to make sure they do so in a clear space, away from buildings and foliage.
Fireworks should also be held firmly in the ground and pointed towards the sky.
In 2014, there were 268 firework-related calls.
