The BP gateway site off the Pacific Highway and Oxley Highway will be officially opened on Tuesday, September 24, after being closed during a complete rebuild since May 26.

Port Macquarie-Hastings mayor Peta Pinson will unveil a new plaque at the site. The service centre held a soft opening on September 17.

BP Gateway's operator Michael Webb said the works have been completed slightly behind schedule, however the site is ready for 24/7 operation in the September school holidays.

"It's probably a week later than what we anticipated. We have done well with the weather considering the whole place has been dug up and rebuilt," he said.

"It hasn't been a renovation, it's been a complete rebuild. We have achieved a lot.

"Holiday travellers start coming through in a week and we always planned to be opened in the beginning of September.

"We will be ready for the holiday period, the Christmas period and obviously Easter as well. That's the best time of the year for us from September to April."

NSW school holidays begin at the end of term three, from September 27 to October 14.

During the redevelopment, the service station has been completely rebuilt and its tanks replaced to allow all fuel products at all pump islands.

"It's serious dollars, I won't put a number on what's been spent but it's serious dollars," said Mr Webb.

"We have new tanks with extra volume after the old ones were pulled out of the ground. We now have storage of 450,000 litres, which is 150,000 more than what we had before.

"We have extended the bowser island to include two extra pumps on the right hand side, that's 64 hoses which people can choose from.

"It's more than adequate. This facility will take us into the next 15 or 20 years hopefully."

Construction works were undertaken by Commercial Project Group, fuel-related works were undertaken by Engineering Mining and Petroleum and the site was designed by architects King and Campbell.

Newcastle resident Luke Wilson was one of the first motorists to use the new facility on September 17.

"We've been through here before, it looks nice and clean," he said.

"We've fueled up here before and got some food. It's a good set up.

"We know this place, Taree and Coffs Harbour are our regular stops.

"We pick this one because it's a good stop for the kids to get something to eat before you get to Coffs Harbour."

There are also future plans to add four electric vehicle rapid fill stations behind the BP Service Station within the next six months. The charging stations have a filling time of eight minutes.

Port Macquarie-Hastings Council originally gave conditional consent for the redevelopment project in 2016.

"Highway traffic is about 60 per cent of our business as a transient stop from Sydney," said Mr Webb.

"Although we are finding we are getting a number of local customers, especially in Sovereign Hills and people travelling from Wauchope to Port Macquarie on a daily basis.

"We are lifting our business with local trade as the months go by. Hopefully we will get the support of the community."
