Neighbours of a Kainga Ora property at the centre of a double police shooting in Christchurch's Bryndwr are questioning why police fired shots

Officers shot and killed a woman, and critically injured a man, at a home on Clyde Road after 11pm.

They say they were responding to reports a man was armed with a knife and threatening to hurt himself and his partner.

The woman was killed after reportedly picking up the knife, and threatening police.

A source has told our newsroom police had been at the property often, recently.

Neighbours say they knew the couple well, and would see them walking their dogs in the area daily.

They're asking why a taser was not deployed.
