Auckland Regional Public Health Service are working to contain a measles outbreak with 48 people currently in quarantine, four confirmed cases of the disease and more cases being investigated following a public health alert last week when a person ignored quarantine instructions.
New Zealand Medical Association chairman Stephen Child joined Paul Henry to discuss the outbreak.
"Some fascinating studies show that if someone has measles and walk out of the room it's still in the room for up to two hours after they leave the room."
He added that it's never too late to get immunised.
