Last week the country's only oil refinery based at Marsden Point ceased operations and became an import-only terminal for already-refined products.
The company that runs it, Refining New Zealand has rebranded to Channel Infrastructure.
It will utilise the existing site to receive, store and distribute transport oils to its customers.
There have been concerns the change alters the country's security of fuel supply, although those fears have been downplayed by the government.
