Horticulture New Zealand hopes Heinz-Wattie's will use Hawkes Bay growers ahead of international competition as the food company moves sauce production to Hastings.
Reports suggested that sauces to be processed in Hastings after the closure of an Australian plant were made mainly from American and Portuguese tomato pastes.
But Heinz-Wattie's spokesman Paul Hemsley said the company would source most of its tomatoes from Hawkes Bay.
He said, however, that demand for tomato paste exceeded the company's ability to find the product locally and so sometimes it had to be imported.
"The important thing is that the seeds from which these tomatoes grow from in other countries are Heinz seeds," he said.
