The cost of fuel is on a downward slide and has reached its lowest point in more than six months.

Falling commodity prices and a strengthening New Zealand dollar are being credited for the price drop.

In October fuel costs fell a total of 8cents per litre.

Petrol is around its lowest price since April, at just under $2(two dollars) a litre.

Diesel is costing just over a dollar a litre, which is its lowest point since February.
