There's a widespread global shortage of ADHD medication - and it's hitting Kiwis hard.

A survey by ADHD New Zealand of people prescribed with ADHD medication found that over half were struggling to get what they needed - and one third of respondents were worried they would lose their jobs if they weren't properly medicated.

ADHD New Zealand spokesperson Darrin Bull says people in schools and universities are also struggling under the current shortage.

"This is a global issue - it's just not New Zealand, there are particular issues in the UK and Australia as well. It's a supply chain issue."
