Costco has revealed its petrol prices at its brand new petrol station in west Auckland, Newshub reports. The station, which opened on Wednesday morning, is across the road from the company’s unfinished warehouse – which will be opening in late August. The US giant is selling in NZ: 91 for $2.50 per litre, 95 for $2.60 per litre and diesel for $2.10 per litre. Costco NZ managing director Patrick Noone says the new petrol station is a huge step closer to bringing Kiwis affordable retail, and creating competition in the market.
