People are traveling from around the world to be treated at a ground-breaking research centre in Christchurch which teaches people how to swallow again.
The University of Canterbury's Rose Centre for Stroke Recovery and Research has developed new techniques which help people who have had a stroke, brain injury or brain tumor how to swallow again.
The team is headed by Professor Maggie-Lee Huckabee who tells Kathryn how the team are treating people who haven't been able to swallow food for years.
