Petrol prices remain low, having fallen consecutively more than 20 times since October.

There is some variation between regions, stations and companies, but fuel is up to six cents cheaper in many places.

That's compared to what it was just a few days ago.

In Dunedin the price of 91 is sitting around $1.70 per litre.

Diesel has also dropped.

The cost cuts are a reflection of low barrel prices for crude oil.

There are suggestions that prices could drop even further, before picking up again later in the year.
