A spokesperson for Fire and Emergency told Newshub the explosion happened on the ground floor of a unit owned by Housing New Zealand.

"We're not sure the cause of the explosion at this stage, it's now a crime scene so police will be doing an investigation into that," senior station officer Brendon Irwin said.

One person is in a critical condition while the other has been seriously injured, police say.

The explosion blew a window out, but didn't cause damage to other units.
