Petrol prices could rise within days in New Zealand as a result of Saturday's attacks by Yemini rebels on Saudi Arabian oil facilities, both BP and the Automobile Association spokesman have warned.
Houthi rebels launched drone attacks on the world's largest oil processing facility in Abqaiq, Saudi Arabia and the major Khurais oil field on Saturday, sparking huge fires.
The Wall Street Journal reported the attacks had shut down half of the country's oil production, which analyst OilPrice.com said would be equivalent to reducing global supply by about 5 per cent.
OilPrice.com suggested oil prices could spike above US$100 (NZ$156) a barrel in the wake of the attacks when oil markets reopened, up from their current price of about US$55 a barrel.

While Saudi Arabian oil company Aramco was confident that it could recover quickly, if it couldn't, the world could face a production shortage that could send oil prices "into the triple digits", it said.
BP spokesman Gordon Gillan said its prices were reflective of the oil price in international markets among other influencing factors "so it is possible there could be an impact on local prices later this week".
BP did not want to speculate further, he said. "We review our BP Connect prices every day so our prices are as competitive as possible."
The cost of fuel only accounts for about a third of the price of petrol, with much of the remainder represented by taxes.
