Petrol prices in Tauranga vary by up to 18c per litre with some stations offering the lowest prices in the country, according to an unofficial Bay of Plenty Times survey.
The unofficial petrol station survey across the city showed that some stations still had their prices as high as 197.9c per litre, which is also the national price for petrol currently, but some as low as 179.9c - an 18c difference.
Mark Stockdale, AA PetrolWatch spokesman, said the petrol prices had been coming down for the last seven weeks with the lowest prices of $1.80 coming from Rotorua and Auckland.
The drop was due to international commodity prices falling which flowed onto lower prices at the pump, he said. The drop meant petrol prices were down 14c a litre.
Mr Stockdale said the low prices would likely continue with commodity prices still dropping.
