Christchurch explosion: Three remain in hospital, two released

Two of those seriously injured in Friday's gas explosion in Christchurch have been released from hospital.

Police say it was a miracle no-one was killed in the explosion. The blast in Marble Ct, Northwood, turned one house to rubble, and damaged surrounding properties.

Some residents from around Marble Ct have returned to their homes, still shaken by Friday's explosion.

Newshub has learned two of those injured in the explosion remain in Christchurch Hospital - one stable and one critical, while a third is stable in Auckland's Middlemore. 

Meanwhile, the Christchurch City Council has confirmed it plans to issue dangerous building notices on four properties that are uninhabitable, a spokeswoman said.

Despite police efforts to reassure residents that gas in the area is safe, a number of residents are not consoled - and no longer want to live there. The whole area opereates on a reticulated gas network. 

A large number of the Marble Ct cordons came down on Monday. Although many residents are now allowed to access their homes, a number of locals never want to live in the neighbourhood again due to the traumatic experience - and anxiety over the gas.

Investigations into what caused the explosion continue on Tuesday as police keep watch over the scene.
