"They were manufactured in a central location and flash frozen with raw pastry then delivered to the restaurants and they baked them off. They were virtually fresh-baked, which is something you can't buy today because most pies are pre-baked, put in a warmer or heated. They also had very thin pastry compared to other pies and they had a lot of meat in them."

By 1993, Georgie Pie was such a success it announced plans to expand into 160 outlets. Then Georgie Pie was bought and sold again, and those plans never happened.

In December 1998, the restaurants closed after McDonald's bought them out.
Although retired, Popham still plays a pivotal role in New Zealand's enduring passion for pastry - he is helping to bring back Georgie Pie. He has been working with McDonald's for months to make sure the pies it will sell at a few select outlets next month are the genuine items.
McDonald's is bringing back the steak mince and cheese pie for a trial from next month.
Apart from taking out one ingredient, MSG, the pies will be made using the original recipe, the flash-freeze system, and the machinery of the original Georgie Pie factory, which is now owned by Goodman Fielder.
The pies will go back on sale at the Greenlane McDonald's - where it all started.
Peter Foster, now a McDonald's franchisee in New Plymouth, has fond memories of his Greenlane Georgie Pie days.
The branch was open 24-7, had two storeys and, on weekends, there would be two birthday parties on the go from 11am to 7pm.

"There's a lot of loyal customers out there who weren't ready for it to go."
