A Qantas flight from Auckland has made a priority landing at Sydney Airport after experiencing a fuel system problem.

The Boeing 737, flight QF50, landed safely about 9.45am (NZT) on Wednesday.

"The flight crew on board QF50 from Auckland to Sydney requested a priority landing at Sydney Airport as a result of a fuel system fault," a Qantas spokesman told AAP.

All passengers disembarked the aircraft safely, he said.

Paramedics had been called to the airport as a precaution but were not required to treat anyone.

The spokesman said the fault was not thought to relate to the aircraft's engines.

Engineers will now examine the aircraft to determine the exact cause of the problem.
