Fraser Cove Jesters Pies worker Tracy Schep said she had heard a man complain of the temperature after biting straight into a pie, but said people needed to be mindful that pies legally had to be served at 65C.
Mount Maunganui Bakery's Heather Herbert said she had the occasional minor burn from ovens but had not seen any customers suffer injuries.
One Dunedin man, 48, who did not want to be named, made an ACC claim after he burnt his oesophagus on the filling of a mince and cheese pie.
He had reheated the pie in his workplace microwave, as he had many times before.
"When I reheat a pie in the microwave, I put it in the same spot and for the same time - 55 seconds."
However, the pie had been off-centre in the machine and heated unevenly. He swallowed a bite, burning himself on the "super-hot" filling.
His oesophagus remained sore a week later and his doctor logged his gullet injury with ACC in case surgery was needed, he said.
Police advice to "always blow on the pie" became famous in 2009 after a policeman advised a potential car thief to "always blow on the pie" in television show Police Ten 7.
