Husband and wife Warwick and Chris Wright aren't your average 68-year-olds.

While others their age holiday via cruise ships and motorhomes, this Omokoroa couple see the world from couch to couch.

Omokoroa couple Warwick and Chris Wright travel the world one couch at a time.

Having signed up with a ‘couch surfing' website, the Wrights travel overseas by staying in strangers' homes – or meeting for a meal or sightseeing – embracing their host's local food, culture and way of life.

'It's a free merry-go-round of about six million people prepared to meet or accommodate you for a time – and vice versa,” says Warwick.

The couple, who also host ‘surfers' in their own Harbour View Rd home, is heading to Uganda in two weeks to witness the marriage of an Ugandan lady they met ‘surfing'.

The Wrights began couch surfing in October 2010, after Warwick stumbled across a Belgium woman's travel blog while planning a trip to South America.

'She said one of the five best things she'd done was join the couch surfing website. I came home, had a look at the site and thought it would be interesting.”

Warwick says the website allows people to sign up to offer accommodation, or meet up, and ask to ‘surf' at fellow members' homes worldwide.

'The ‘couch' may be just that, or can be a private bedroom.

'It's not compulsory to accept a request, and the length of time for hosting is up to those involved, but is usually one-three days.”

The couple hosted their first surfer in late 2010 and first went ‘surfing' to Australia, Sarawak and Mauritius in 2011.

It's snowballed from there. They've now hosted couch surfers – aged 18 to 72 – more than 200 times.

And they've ‘surfed' Australia, Europe, China, South Korea, Malaysia, Taiwan, Indonesia, Mauritius, Rwanda, Uganda and New Zealand.

Warwick says to go couch surfing you have to be a risk-taker 'because it's a bit scary early on, meeting people when they come to your house”.

'We were even more apprehensive when knocking on a door and saying ‘Hi, we're the people you've been messaging'.”

Warwick says it's completely changed the way the couple think about travel – they now meet up overseas with surfers they've hosted.

When hosting, the Wrights pay for 60-70 per cent of food.

'Surfers like to cook their specialty food for the host. We've cooked pavlova, and made bacon, banana and maple syrup pancakes in so many homes.

'We'll keep doing this as long as we're fit enough.”
