There's been a spike in measles cases in Otago-Southland but the DHB says it needs to prioritise the vaccine.
In the past 48 hours 13 new measles cases have been confirmed in Queenstown, two in Wanaka and one in Dunedin.
The Southern DHB says people who had measles and were infectious at the time visited many Queenstown restaurants, ski fields, parks and shops over the last few weeks.
Lisa Owen asks the Southern DHB's Medical Officer of Health Dr Susan Jack for the latest.
