Much of the work under-pinning the recent discovery of so-called "gravitational waves" could also be traced back to his seminal theoretical work more than 50 years ago.
The team of physicists that confirmed the existence of gravitational waves -- ripples thorough our universe that have only been theorised until now -- concluded that they were produced during the final fraction of a second of the merger of two black holes to produce a single, more massive spinning black hole.
This collision of two black holes had been predicted by Professor Kerr, but had never observed.
Professor Kerr, who now lives in rural Bay of Plenty, retired as Professor of Mathematics at the University of Canterbury in 1993 after 22 years, including a decade as the head of the university's mathematics department.
Earlier this year, he was also awarded the University of Canterbury's rare honour of Canterbury Distinguished Professor.
The academic title awarded to Emeritus Professor Kerr was the highest that can be awarded by the university's council and has been conferred just twice in its near 150-year history.
