Kiwi boxing great David Tua has been videoed coming to the rescue of a woman whose car was stranded with a flat tyre.
But the woman had no idea that heavyweight boxing royalty had been her Good Samaritan.
Twitter user @NicoleWhippy recounted her friend's story, together with a picture of 48-year-old Tua changing her tyre, while talking her son through the process.
"My gf gets a flat tyre while out with her young son and she doesn’t know how to fix it," Whippy tweets.
"A couple in a car pull over to help her. The man not only changes it, but takes the time to teach her six-year-old son what to do."
The woman was brought to tears by Tua's generosity, promoting her to snap a picture of the moment, completely unaware of his standing as an NZ sporting legend.
"She is so touched by this man's kindness she starts crying," Whippy continues. "She posts this photo of the moment.
"She had no idea it was David Tua."
Tua is regarded as arguably the best Kiwi boxer to ever grace the ring. In his prime, he was considered one of the most powerful punchers in the sport, amassing a 52-5 professional record and earning a world heavyweight title shot against Brit Lennox Lewis.
