Energy Minister Judith Collins has signalled that an inquiry into rising petrol margins could be launched next week.
The Automobile Association today called for fuel companies to explain to motorists why the national price of fuel rose 5 cents per litre during January, despite no increase in commodity prices or a drop in the exchange rate.
Collins, who became Energy Minister at the end of 2016, said ensuring a competitive market was the best way to keep fuel costs down and she would be discussing this with Ministry of Business, Innovation and Employment officials today.
``I will be taking some suggestions through to my colleagues, but I think there will be some actions announced next week,'' Collins told Fairfax.
``I am like any other person in New Zealand concerned if these margins continue to rise when there seems little justification for it.
``I will get to the bottom of this and next week I expect to have something to announce.''
