Fireballs
Turns out it was fireworks being let off at a local school, a spokesperson for the New Zealand Fire Service said.
People streamed out onto the mean streets of Ponsonby on Saturday night to check out the boom. One bar emptied and the wall shook.
But residents and reveller are still unclear what caused it.
A Ponsonby resident say they heard a "massive explosion" between 7.30 and 7.40pm, causing neighbours to rush onto the street to see what happened.

The meteor (pictured) was seen in different parts of New South Wales at around 6.30pm last night, leaving locals mystified
The meteor was seen across the city at around 6.30pm, with some lucky witnesses managing to capture incredible footage of the rare phenomenon.
Footage circulating on social media showed the fireball slowly growing larger and more visible as it streaked through the night sky.
The moment only lasted for a few seconds before the flash of light was gone.
1 Introduction
After two disappointing months, December 2017 and January 2018 with the most unfavorable weather possible for meteor video work, the poor weather continued the first few nights of February 2018 until a major improvement changed the situation from 5-6 February onwards. The month of February is a winter month with long nights in the BeNeLux while meteor activity is still fairly high. The weather used to be favorable during the years 2014, 2015 and 2016 when the network counted much less cameras than today. February 2017 was characterized by very bad weather circumstances with as many as 12 nights without any single orbit. What did February 2018 bring?

The event was recorded in the towns of Yugansk and Surgut on Saturday night. People gazing at the fireball and watching the videos have been guessing if that was a meteor or maybe a UFO.

The Perseids is a prolific shower of fiery space particles that has streaked over our planet annually for generations as Earth encounters debris falling off the Swift-Tuttle comet, which was first discovered back in 1862.
The gleaming debris is generally first seen in mid-July in the northern hemisphere but enters a particularly sweet period of viewing for amateur stargazers between August 11-13, 2018. According to NASA, the peak period happens around a moonless night when the sky is darker than normal.
"Unlike most meteor showers, which have a short peak of high meteor rates, the Perseids have a very broad peak, as Earth takes more than three weeks to plow through the wide trail of cometary dust," said Jane Houston Jones, of the US space agency's Jet Propulsion Laboratory.
The curious tweet was released by Ron Baalke, a space explorer at NASA's Jet Propulsion Laboratory, in late July. "A fireball was detected over Greenland on July 25, 2018 by US government sensors at an altitude of 43.3 km," he wrote. The energy from the blast was estimated to be 2.1 kilotons.
Community social media pages lit up with posts about the meteor about 7pm.
Jason Jaques, of Mareeba in Cairns, was on his way to pick up a pizza when a flash of light caught his eye.
"It was a green fireball, it was very bright and it caught the corner of my eye," he said.
Mr Jaques' dashcam footage of him driving out of his coffee plantation is the only video footage of the meteor that has emerged so far.

Residents in Folly Beach, on James Island and in West Ashley all say they either heard or felt it.
