The company has decided it is best to split the production lines for home delivery and the rest, which is why stores have been configured with double cooking and handling facilities and both sets of customers will be given priority, he said.
Restaurant Brand has 42 KFC stores in New South Wales through its A$82.4 million purchase in April of independent franchisee QSR and is actively seeking to buy other independent franchisees in that market.
There's an opportunity to introduce home delivery through those Australian stores if the New Zealand trial proves successful, Creedy said.
Fast food operator McDonald's began delivering hamburgers out of its New Lynn restaurant this week and will do so from its Glenfield restaurant from next week.
The service is only available in the evenings between 5pm and 10.30pm and to households near each restaurant.
Pizza Hut has also done home deliveries for years but Creedy said he doesn't think it would work for Carl's Jr because "burgers are best eaten fresh".
The company said it would be watching with interest how the rival chain's home foray pans out.
The shares fell 0.7 per cent to $5.41 today and have gained 22 per cent this year, outpacing the S&P/NZX 50 Index's 14 per cent gain.
