A University of Otago report showed asthma in Whanganui to be the highest in the country killing around six and hospitalising more than 160 locals each year.
The report, conducted for the Asthma and Respiratory Foundation NZ, showed asthma prevalence of Whanganui's children to be over 23 per cent which is almost 9 per cent higher than the national average.
Associate Professor Jim Reid from Otago University said with yesterday being World Asthma Day it is a timely reminder for us all to put asthma and the seriousness of the disease back into the spotlight.
"More research is needed to understand why New Zealand has such a high rate of asthma and also to explain why some children seem to grow out of the disease."
He said the incidence of asthma is particularly high among Māori and Pasifika communities and those living in poverty.
