More than 208,000 New Zealanders have diabetes, many of whom are at risk of potentially fatal complications.

"I've been a type one diabetic for 27, coming up 28 years," said Fergusson. "The struggle for me is having regular low blood sugars, despite having regular blood sugar testing."
In the not-too-distant future, Fergusson could have the aid of diabetic response dog to indicate when her blood-sugar levels are awry.
Marika Bell from the Kotuku Animal Foundation is currently training a German Sheperd to sniff out when a diabetic has dangerously low blood-sugar levels.
Former police dog 'Uni' is taught to target a "scent stick", which he presses his nose against.
"He starts to really look for that smell, and that's how we create scent discrimination for a dog, who hopefully will be an alert dog for a particular type of disease," said Bell.
Fergusson is sending Uni's trainers samples of her clothes that contain sweat resulting from one of her low blood-sugar attacks.
The idea for diabetes response dogs is new in New Zealand; Uni will be the first one in the country if he passes the stringent tests.
Uni still has a year to go before he is ready for the
