An aircraft has slid off a runway at Christchurch Airport during landing.

Freelance Journalist Diana Clement was a passenger on the plane and says it was a frightening landing.

"We swerved off the runway onto the grass then swerved violently back onto the runway before coming to a halt across the main runway."

Clement told Morning Report they were told there had been a hydrolic leak on the right hand side.

"Everyone's feeling a bit shaky."

The flight itself did not feel out of the ordinary, she said.

The incident happened at 7:45am on Friday.

Emergency services were at the scene.

There are no reports of injuries.

Several domestic arrivals and departures to Christchurch have been cancelled.

One passenger told the NZ Herald "something went horribly wrong".

"We ended up on the grass," they said.

The Jetstar aircraft will be towed to the gate for passengers to disembark.

Planes are circling along the East Coast unable to land due to the incident.

These are flights from Tauranga, Auckland, Wellington, Queenstown, Palmerston North and Singapore
