A Pacific Blue plane bound for Wellington made an emergency diversion to Christchurch.

A Christchurch Airport spokeswoman confirmed the plane landed safely at 12.30am today.

"All I know is that we enacted our standard emergency procedures because we were alerted to a potential problem on the plane."

"Fortunately a very happy ending on February 22."

A Wellington Airport spokeswoman confirmed the plane was a Pacific Blue aeroplane, but could not say where the plane had come from.

She said no information was available on what led to the diversion.
