It was hard to predict at what point the prices would stop rising.
“I expect every week there will be a slow increase for at least the next month or maybe longer,” he said.
There would be a flow-on effect from the northern hemisphere and how much demand there was for fuel for heating, Mr Collins said.
One of the main reasons for the present lift is that the Government’s 25 cents a litre tax cut imposed in March 2022 ended on June 30 this year.
Originally intended to last for three months to reduce pressure on households, the cut was extended several times but the Government says it is no longer sustainable.
The end of the excise tax cut immediately added up to 29 cents a litre on petrol.
Gaspy, the New Zealand app that tracks prices throughout the country, says the New Zealand dollar is not helping.
Spokesman Mike Newton said the average petrol price has risen by $2 a litre for 91 grade petrol to more than $3 in most parts of the country.
He said the things that seemed to be pushing up prices were the NZ dollar and the cutback in supply from OPEC. These things were out of our control.
Who knows where or when things are going to turn around? We are approaching the point where the fuel excise was first removed in March last year.
For this district fuel increases quickly translate to other price increases in the rurally based economy.
The timing of the increases could not have come at a worse time for the Government, just over three weeks from the election.
Whoever wins, the pain at the pump is going to continue.
