Mr Berryman was shouted a birthday trip on Wanaka pilot Robert Broek's 1944 P-51D Mustang by his former colleagues at the now disestablished New Zealand Fighter Pilot's Museum at Wanaka Airport, where he was a volunteer visitor guide for about 24 years.
The last time Mr Berryman flew a fighter plane was in the mid-1950s when stationed overseas with the Royal New Zealand Air Force. At that time, he was piloting Vampires and Venoms during postings in Cyprus and Singapore.
"I got to like it very much," Mr Berryman said of his time spent squadron flying and performing aerial displays in Mustangs.
After leaving the air force, he spent about seven years working as an examiner for the Civil Aviation Authority of New Zealand, before a 15-year stint as a commercial pilot with Mount Cook Airlines.
His final job in the aviation industry was as a flight simulation instructor based in Christchurch and Auckland, for about a decade, until the early 1980s.
After moving to Wanaka in 1986, Mr Berryman began voluntary work as a Fighter Pilots Museum guide, showing a devotion to the role which earned him much respect from fellow museum staff and prompted them to pay for the Mustang trip.
"I enjoyed it tremendously," he said of the Saturday evening flight which took him over Wanaka, Hawea, Cardrona, Queenstown and Glendhu Bay.
Mr Broek had even included a roll of the aircraft for good measure, Mr Berryman said.
"It wasn't a very vigorous one. It was nice and quiet for the old bloke in the back seat."
While he "didn't get all weepy about it", Mr Berryman said the flight brought back plenty of memories, "most of them pretty good".
He had even asked to do the flight all over again on his 90th birthday, his wife Thea Tebbutt said.
Mr Berryman gave "immense" thanks to his former museum workmates for the opportunity to relive his fighter pilot days.
Mr Broek, whose Mustang is used primarily for aerobatic displays and air shows, said it was "a privilege" to take Mr Berryman on the flight.
"He's a living legend and one of the very few left who's seen war time activity . . . so for me to take him up now was really quite a special occasion for me and the fact he enjoyed it was a bonus," Mr Broek said.
