All Black hero Zinzan Brooke, one of the world's most famous former flankers, is championing the Steinlager All Blacks gourmet burger, made with 100% Aberdeen-Angus Scotch beef, beetroot, egg, pineapple, matured cheese, salad and relish.
Zinzan said: "Rugby players typically burn about 880 calories an hour in play, so it is essential to eat food that's a rich source of energy and protein and the Steinlager All Blacks burger certainly hits the spot. Perhaps one of the secrets to the success of New Zealand athletes is their love of pure, delicious foods that taste great."
A spokesperson for the Gourmet Burger Kitchen said: "There are 32 Gourmet Burger Kitchen restaurants in England. As well as the business employing many New Zealanders and Australians, the famous New Zealand chef Peter Gordon helped create the recipes.
"England, Scottish and Welsh rugby fans who cannot stomach any kind of support for their All Blacks opposition need not worry as they have 27 other choices of gourmet burger from a plain Classic to a Chilli, Cajun, Blue Cheese or Jamaican."
A competition with a prize of a flight for two to New Zealand (courtesy of Air New Zealand) plus £2,000 cash is running for those who buy a Steinlager All Blacks burger for the duration of the Rugby World Cup.
