Health advice:

People have been told to stay inside to avoid smoke inhalation.

Dr Alistair Humphrey, Canterbury Medical Officer of Health has advised that anyone suffering respiratory issues contact their GP.

"For the vast majority of people, the smoke will be unpleasant, but carries no risk to their health. However, smoke may irritate the eyes, nose, throat and airways. More serious symptoms include runny or sore eyes, dry or sore throat, sore nose, cough, tightness of the chest or difficulty breathing.

"In healthy people, most symptoms disappear soon after exposure to smoke ends and do not cause long-term health problems."

Cigarette smokers, the elderly, children and those with heart disease, asthma or other lung disease are at greatest risk of harm from smoke inhalation.

"Avoid exposure where possible by staying indoors and closing windows and doors," he says.
