Otago University research has found significant barriers to effective treatment - including cost, long wait times, and lack of access to specialists.

More than 750-thousand Kiwis experience migraines.

But study co-author Jonathan Kennedy says there's a shortage of neurologists, and lots of pressure on GPs.

He says there aren't enough specialist appointments available, and patients consulting GPs need better access.
