Update 10.00am: Firefighters are at the scene of an oil spill from a truck in Mount Maunganui.

Fire and Emergency New Zealand communications northern shift manager Colin Underdown says the oil has come from a truck's spilled fuel tank.

"We are currently damming it," says Colin.

"The time on clearing it will depend on how big the spill is and where it has gone. The council will check the stormwater drain and we will clear the road itself."
