Head judge Tim Aspinall and guest judge Martin Bosley talk about the Bakels pie awards judging process.

A potato-top pie has won the top pie award at the 19th annual Bakels New Zealand Supreme Pie Awards.

The tasty treat, from New World Greenmeadows bakery in Napier, beat 512 other competitors at the gala dinner on Tuesday night.

Judges described the pie as a "perfect ratio between a flavoursome filling, a super creamy potato top, and a delicious pastry shell."

iStock More than 510 pies were entered in the competition.

Top chef and judge Martin Bosley hadn't expected to be blown away by such a normal pie.

"I was immediately transported to my grandmother's kitchen as a young boy when she would cook up her famous shepherd's pie for the family," he said.

"I was won over by how every aspect of the winning pie was executed to equal perfection."

Chief judge Tim Aspinall, who's been in the pie-judging business for 12 years, said selecting a winner was challenging.

"Pie entries need to meet myriad criteria," said Aspinall.

"From pastry to presentation to flavour."

The panel of 21 judges spent more than 10 hours on July 16 judging 5200 pies, which were blind coded in 12 categories, including the new Kiwi favourite Potato Top Pie category.

Forty-nine awards were presented at the awards gala dinner at Auckland's Shed 10, hosted by Dominic Bowden.

The baker of the Supreme Pie walked away with the coveted Supreme Pie Maker trophy and $7,500, while Gold award winners received $1000.

Two supermarkets received gold awards (Pak'nSave in Petone and New World in Napier).

An Auckland bakery, Dairy Flat Bakery, received two gold awards: one for the best gourmet meat pie and another for the best gourmet fruit pie.
