NZA study conducted by Otago University researchers found that autism spectrum disorder (ASD) diagnoses in New Zealand have more than tripled over 15 years, according to data analyzed from 2009 to 2023. The research, published in The Australian and New Zealand Journal of Psychiatry, revealed that over 30,800 individuals received an ASD diagnosis during the study period, with prevalence rates reaching 1.3% among children and 0.14% among adults by 2023. Diagnoses increased across all age groups, genders, and ethnicities, with notable rises among Māori populations and those in socioeconomically disadvantaged areas. Researchers attributed the surge to factors such as heightened awareness, expanded diagnostic criteria, improved access to assessments, and potential environmental or societal influences. They emphasized the need for increased investment in autism-related services and workforce training to meet ongoing demand, noting that autism is a lifelong condition requiring support throughout adulthood.
