The boss of a Z Energy rival says its planned acquisition of Caltex operator Chevron NZ could impact competition in the fuel market.
But Dave Bodger, general manager of the Gull service station chain, says he expects the Commerce Commission to conduct a thorough assessment of the deal.
Z will end up with a 49 per cent share of the fuel market if the $785 million sale, which requires the competition regulator's approval, goes ahead.
Bodger said his firm was assessing the potential impact of the acquisition.
He noted that Z had indicated it could divest assets included in the acquisition if the commission requires that, which could improve competition in some regions.
