The use of fireworks is not banned during a prohibited fire season, as the changing 'seasons' - which are decided by Fire and Emergency New Zealand - only relate to open-air fires.
The large fireworks display at North Hagley Park will be part of the annual YES Power Sparks, previously known as Sparks in the Park.
The display will still go ahead this weekend, Christchurch City Council manager events and arts Lucy Blackmore confirmed.
FENZ hold the power to prohibit or restrict spark-inducing activities, such as fireworks, under Section 52 of the Fire and Emergency New Zealand Act 2017.
Said North Canterbury principal rural fire officer Bruce Janes: "We expect those planning to use fireworks to understand how dangerous they can be and not use them during restricted and prohibited seasons.
"A significant number of vegetation fires are caused by fireworks," Mr Janes said.
Said Ms Blackmore: "The council events team is working closely with Fire and Emergency New Zealand to plan for the Sparks event.
"Extra precautions have been put in place and we will continue to monitor conditions."
Event organisers are anticipating a crowd of 50,000.
In spite of having the appropriate permits to host a public fireworks display, Kathmandu Coast to Coast organisers, Go Canterbury, decided to cancel its display for the New Brighton event last Saturday.
"We thought it was the right thing to do," a Go Canterbury spokesman said.
Event sponsor, ChristchurchNZ, said the display was cancelled "due to a number of reasons".
Usually to apply for a permit for a public fireworks display, event organisers will have to provide a site plan, outlining the proposed area for the fireworks display, a detailed list of all fireworks to be used, written approval from FENZ and a copy of a hazardous substances and new organisms (HSNO) test certificate for the pyrotechnic display prior to the event.
