Two major fuel companies say they're concerned about the supply chain in Christchurch and are seeking the city council's support as they develop new fuel transport routes and facilities.
BP New Zealand and Z Energy presented their case to councillors on Thursday saying there is significant investment uncertainty for oil companies at present.
BP national terminals manager Warren Bolger says one of the main routes via Evans Pass has been unusable since the earthquakes, forcing trucks to use the Lyttelton tunnel at night, under strict conditions.
Mr Bolger wants continued use of the tunnel to be allowed until the pass is reopened and alternative routes are created.
The executives did not ask for funding, but rather the ongoing support of the city council as they redevelop the damaged fuel supply chain.
