Mr Kloeg's winning creation was named top pie at tonight's awards dinner in Auckland.
It was picked from more than 4800 pies by the 24-strong judging team, which spent a day assessing the entries from 533 bakeries around New Zealand.
Exotic pie flavours included rabbit and wild boar, caramelised rhubarb and wild berry, chilli con carne, spiced duck with bacon and slow cooked beef cheek and cauliflower cheese pie.
Mr Gault commended the bakers for this year's "top standard".
"I could imagine the gold category winner pies being served in a restaurant," he said.
"From my end, it was very difficult to judge, which is always a good sign.
"It was hard to make the final decision because I know there's a lot riding on these awards. Bakers' reputations are on the line," he said.
Chief judge Tim Aspinall said a good pie made people think: "man, I would like to get into that".
"It has to have a good glaze, rich colour, a nice shape and some lift in the pastry."
"Then, whatever the main ingredient is has to be there in substantial proportions. If it's a mince and cheese, then the mince has to be the bulk item - you need to be able to bite into the pie without it oozing out. If it does that, then there's too much gravy," Aspinall said.
For the judging, which took place on Thursday, the pies were blind coded into 12 categories, which included mince and gravy, steak, vegetables and gravy and steak and cheese.
As well as the supreme pie award, a winner was chosen for each category.
This year's entry total of 4832 pies was 5 per cent more than last year.
