Yesterday, coastal vessel Matuku unloaded 36 million litres of petrol and diesel at the port.
Tankers would be operating 24/7 to deliver it to Auckland.
Port of Tauranga chief executive Mark Cairns said fuel tankers generally called at the port every 10 days.
"We are not seeing any increased frequency at this stage, rather that the vessels are coming in more heavily laden and exchanging greater discharges."
He could not disclose normal shipping volumes due to commercial sensitivity but said the port handled around 1.5 million tonnes of oil products annually.
The crisis was sparked by the discovery of damage to a section of the pipeline that directly connected the Marsden Point Refinery to Auckland International Airport.
The pipeline was shut down last Thursday.
