Authorities working to contain the Port Hills fire are being helped by drizzle, which is forecast to turn to light rain this afternoon.
Civil Defence said in a statement that protection of property remained a high priority, with firefighters working to black out the fire perimeter.
The Fire Service remained concerned about the area around Victoria Park and east of Dyers Pass Rd.
The area had terrain and vegetation suitable for fire spread. However, favourable conditions of drizzle and light rain with north easterly winds were forecast for later today.
Geotechnical experts were continuing work to assess the risk of rock-fall in areas where there had been significant loss of vegetation.
