The scale of the Christchurch Port Hills fire is so immense the smoke from it can be seen from space.
The firefighting effort has already claimed one life - that of former SAS soldier Steve Askin - and has destroyed homes and forced the evacuation of around 1000 residents.
The countless photos taken of the 1800 hectare fire only go some way to showing how ferociously and quickly the fire has spread as it rages on into its fourth day.
Here are some of the best photos which capture the destruction and the vast efforts emergency services have gone to stop it.
