The owner of KFC, Pizza Hut, Carls Jr and Starbuck stores in New Zealand has reported a 5.8 percent increase in second quarter sales. Revenue grew by $5.9 million.
Restaurant Brands says revenue grew by $5.9 million to $108 million for the 16 weeks ended early September.
KFC gets most of the credit for the group's sales boost, with sales rising $5 million to more than $80 million going through the colonel's tills.
Compared with the same months last year, the rate of growth has almost tripled at the fried chicken stores from 2.4 percent to 6.7 percent.
Restaurant Brands said the secret behind KFC's success is a refreshed menu which offers new family meals.
The Double Down - a sandwich using meat instead of bread with bacon and cheese which the fast-food outlet describes as a "sensation" - continues to sell well.
Meanwhile, sales at Pizza Hutt stores open at least a year have gone up by more than $1 million to just over $15 million.
The chain has reduced the number of its owned-stores by three to 49, as it continues to sell outlets to franchisees.
Over at Starbucks Coffee, sales were up 1.8% to $7.5 million, despite store numbers dropping by two to 26 compared with the same time last year.
Burger outlet Carls Jr was another encouraging performer for Restaurant Brands, contributing $800,000 to its overall sales total.
Financial results for the first half year will be released on 23 October.
