Sixteen fire appliances have contained multiple fires which broke out in Christchurch's Port Hills overnight.
This morning firefighters who remained overnight were working on dampening hotspots.
Last night Fire and Emergency New Zealand said crews were fighting the fires in the Coopers Knob area above Summit Rd.
A spokesperson said the fires were "substantial" but there was no accurate size of them yet. It was not known whether any official evacuations were taking place.
