Motorists should have noticed some savings at the pumps in April as petrol prices reached their lowest levels in nine months, according to the Automobile Association.
The AA said petrol prices fell 12 cents last month, with 91 octane down to $2.05 per litre in the main centres. Diesel dropped 10 cents per litre to $1.42 a litre at most service stations, the lowest price since July 2012.
This time last year, Kiwis were paying $2.20 a litre for 91 petrol and $1.57 a litre for diesel.
Mark Stockdale, AA's PetrolWatch spokesperson, said petrol prices have fallen 16 cents per litre and diesel 13 cents since mid-March.
"However, the AA's monitoring of commodity prices shows that since the last retail price increase in mid-February, the imported cost of petrol has fallen nearly 19 cents per litre, and diesel 16 cents," Stockdale said.
