Kiwi scientists are paying tribute to one of the greatest minds in modern history.
Astrophysicist Stephen Hawking has died in his Cambridge home, aged 76.
He was diagnosed with motor neurone disease in 1963 at the age of 21, and given only two years to live.
Distinguished Professor at Canterbury University Roy Kerr met Hawkins many times and had dinner with him last year.
He told Mike Hosking his spirits remained high, despite the only remaining function being the muscle in his cheek.
"His sense of humour was so, so witty. It was just amazing, and he was just one of the most astounding humans the world has ever seen."
