A student from Hunterville School is the latest winner of the Colour Your Classroom competition.
Nearly 800 entries were received from across New Zealand, with students explaining, in 300 words or fewer, what they would invent to make life easier for people.
Overall winner, 12-year-old Hunterville School pupil Jordan Hughes, came up with a stellar invention - a health monitor that would be implanted in the wrist to measure levels of the likes of sugar and oxygen, with results sent to a database via Bluetooth.
"This chip could help keep you fit and healthy by making sure you have the right amount of things in your blood and body," Jordan wrote in his entry.
"The chip could give warnings about leukaemia, hematologic diseases, stroke and heart attack."
