All tied up for a good cause

If you're going to tie yourselves together, you better hope you get on with each other.

Three St Matthew's Collegiate pupils decided to go one better with their 40-hour Famine endurance by roping themselves together over the weekend.

The three chums were spotted drawing curious looks as they carefully navigated Plunket's Monster Garage Sale in Martinborough on Saturday.

Paige Hudson, Ella Parkinson and Madi McDonald, all 13, said they did it to appreciate what it was like to live in confined spaces in Papua New Guinea.

The three chums also did the 'famine' over the 40 hours.

World Vision's 40-Hour Famine traditionally involves going without food and collecting sponsors.

But participants can opt for other hardships, like not having cellphones or a vow of silence.

Ella said they had seen a video at school of a family living in Papua New Guinea.

"They have really small houses, really cramped.

"We wanted to see what it was like, living in cramped spaces. So we're giving up our personal space."

Paige said the hardest thing about the challenge was walking at the same time.
