The Air NZ plane had to make an emergency landing at Tauranga Airport.
"I could see some smoke and then the whole plane was freaking out."
That's how passenger Hannah Cheal described the terrifying moment she realised something was wrong with the plane she was travelling on from Wellington to Tauranga.
She was one of 41 passengers on board the Link Air NewZealand aircraft which successfully landed at Tauranga Airport today after one of its engines had to be shut down. The cause of the shut down was not yet known.
Shaken by the experience, Cheal said the plane was while flying over mountains when she felt a bang and could see smoke coming from one of the engines.
"The plane vibrated for a good 10 minutes, and then I opened the window [shade] and saw the engine had just stopped working.
"There were two ladies in front of me that were scared and started crying, so I just tried to encourage them."
He said the pilots deserved a lot of praise for getting all the passengers on the ground safely.
"I have been in worse landings, and this one was great considering what happened."
An Air New Zealand spokeswoman said pilots chose to shut down one engine on the plane as a precaution after an indication in the flight deck of a potential issue with the engine.
Q300 aircraft are designed and certified to operate safely on a single-engine and pilots are trained for this scenario.
"In line with standard procedures, airport-based emergency services were on standby as a precautionary measure," she said.
She said it was not an emergency landing and engineers will inspect the aircraft.
A Tauranga Airport Rescue Firefighter said one engine had to be shut down and the landing was safe.
He said there were 41 passengers on the plane and had disembarked - none appeared to be injured.
A police media spokesman said police were on standby at the airport for if they needed to assist firefighters.
One flight from Tauranga to Wellington has been cancelled as a result of the landing.
Tauranga Airport manager Ray Dumble said he was happy with the way the airport handled the situation.
Dumble said if he recalled correctly, this was the first time this it had happened in his 17 years working at the airport.
Civil Aviation Authority (CAA) senior communications Blake Crayton-Brown said situations like this are investigated in the first instance by the airlines.
