In 2016, Restaurant Brands shares jumped 9.8 percent on the news that it had purchased New South Wales largest KFC franchiser, QSR Pty Ltd, for A$82.4 million in cash and scrip.

During that period, Pizza Hut operated as a dine-in family-oriented restaurant serving alcohol, pasta, salad bars and desserts.

[8] After the acquisition, Restaurant Brands changed Pizza Hut from a dine-in business to a home delivery and takeaway operation commencing 1998.

[10] In late September 2024, Pizza Hut celebrated the 50th anniversary of its establishment in New Zealand by holding pop-up lunch and dinner buffet and dessert events in Auckland.

[12] In 2013, Restaurant Brands hinted at the possibility of further expanding and introducing Taco Bell to New Zealand, saying it could be achieved within the next year or two.

Speculations resurfaced in 2015 when a Taco Bell-branded sign appeared on a Ponsonby Road storefront, later revealed to be a hoax.

[13][14] Speculation of Restaurant Brands acquiring the New Zealand Taco Bell rights has risen after the announcement in 2017 that the Auckland-based company had acquired a Hawaii-based fast food operator of the Taco Bell brand, among others, that operates in Hawaii, Guam, and Saipan.

[18] In 2002 Restaurant Brands expanded its operations overseas with the acquisition of 52 Pizza Hut stores in Victoria Australia.

The Victorian operation ultimately proved unsuccessful, with Restaurant Brands exiting the Australian market entirely by early 2008.
