We're appealing to the public to resist the temptation to come up for a look. Residents in these areas do not want rubberneckers, this includes mountain bikers and runners," said Civil Defence Controller Malcolm Johnston.

The fire began as two blazes on the afternoon of February 13: the first one in Lansdowne on Early Valley Rd, and a second one that started in a car park near Marleys Hill, off Summit Rd.
Two days later, they had combined into one large inferno and a state of emergency was declared.
Nine homes were destroyed and two were badly damaged as the fire spread across the area.
Helicopter pilot and former SAS war hero Steve Askin died a day after the fires started while helping with efforts to put them out.
He was farewelled in Christchurch on Monday.
