Bear Grylls has shared his tips for surviving in the wild with fans across the world, but now he'll be telling you how to fasten your seatbelt, clip your tray table back, and make sure your seatback is upright ahead of take-off.

The Bear Essentials of Safety video rolls out across the Air New Zealand fleet from today, and features the Man vs Wild star running through safety advice for passengers.

"Seeing as you're waiting to take-off, I'm going to run through you a few of the safety drills I've picked up on my adventures," Grylls says while making his way along part of the Routeburn Track near Fiordland.

"First up, make sure anything you're carrying is safely stuffed in the lockers overhead. Lockers in the wild are pretty hard to find."

The adventurer is joined in the video by renowned Kiwi entomologist Ruud Kleinpaste (also known as the Bug Man) and three New Zealand scouts William Hamilton, Connor Moffat and Asha Stevenson. Grylls is chief scout of the UK Scout Association.

"New Zealand is a country that I have always called my home away from home and I feel so proud to be involved with this campaign. We shot in a truly amazing setting with an amazing team - and that is always a privilege."

Previous Air New Zealand safety videos have featured the All Blacks, Paul Henry, Lindsay Lohan, Snoop Dogg, cast and crew from The Hobbit and fitness guru Richard Simmons.

Air New Zealand chief marketing and customer officer Mike Tod said Grylls was the ideal in-flight safety ambassador.

"Bear was the ideal partner to help us bring to life important on-board safety messages in a unique and compelling way, while at the same time demonstrating the best of what New Zealand has to offer. We hope the global attention this safety video will receive generates more awareness of our amazing country and gets a few more bums on seats."

Mr Tod says the video would not have been possible without the support of the Department of Conservation.
