NZX-listed Restaurant Brands - which operates Pizza Hut, KFC, Starbucks and Carl's Jr - reported more modest same store sales growth of 5.3 per cent for its stable in the last financial year.
And Pizza Hut's same store sales grew by only 2.6 per cent.
Domino's chief executive Don Meij said around one-third of Domino's growth was being achieved through market share gains from its direct competitors and expansion in the overall pizza category.
But the rest, he said, was coming from market share gains outside the pizza market.
"Whether it be hamburgers, fried chicken, sandwiches ... we're picking up bits and pieces from all of that," Meij said.
"In New Zealand we're into our fourth year of double-digit growth so we're having a fantastic time."
The company holds the master franchise rights for the Domino's brand in Australia, New Zealand, France, Belgium, the Netherlands, Japan and Germany.
Meij said Domino's had lifted the projection for its future store count across Australia and New Zealand from 900 to 1200 outlets in order to take advantage of the "huge market opportunity".
The company is targeting opening another 100 stores in this country.
The company gave guidance for net profit growth of around 30 per cent in the 2017 financial year, with same store sales growth across Australia and New Zealand expected to slow to 10 to 12 per cent.
