Christchurch explosion: Charges laid over last year's massive blast

Charges have been laid against two defendants concerning a large gas explosion in Christchurch in 2019. 

The explosion happened on Marble St in the suburb of Northwood last July, injuring several people and destroying a house. Surrounding properties were also damaged and police said at the time it was a miracle no-one was killed.

"When you look at the footage, that is a miracle," Canterbury Metro Commander Supt Lane Todd said last July.

Following a WorkSafe-led investigation, it was announced on Thursday a first court appearance has been set down for next month.

"Charges have been filed under the Gas Act 1992 against two defendants following the incident in which a gas explosion caused serious harm to several individuals," WorkSafe said in a statement.

"As this matter is currently before the court, WorkSafe is unable to provide any further information."

Immediately after the explosion, locals Newshub spoke to described the explosion as unlike anything they had ever heard.

"Initially I thought a plane had come down," said Northwood resident Faye McGill.

"It rained glass and shingle through the house," McGill said last July.

The first appearance is set for August 18 in the Christchurch District Court.
