Shredding for a cause: Wellington scrap yard partners with charity for Christmas fundraiser

Stuck on what to buy this Christmas? Why not give someone the rare opportunity to crush a car.

A Wellington scrap metal yard has partnered with a foodbank charity to auction off the experience of feeding an old car through their shredding machine, something they say is a once-in-a-lifetime opportunity.

From an entire car to a million tiny pieces.

"A whole car can be over and done within one minute, two minutes," Macaulay Metals managing director Jeff Harris said.

It's not a long time but "it's an exciting thing to operate", Harris said.

And the experience could be yours. The chance to learn how to operate Macaulay Metal's $15 million shredding machine is up for auction.

"Somebody can buy that car on Trade Me," Harris said.

"Feed it through our shredding plant and get the satisfaction of running a seriously big, aggressive, violent machine."

"I think in the last three or four years life has been pretty tough for people and I couldn't think of anything better than completely destroying a vehicle," Macaulay Metals operations manager Glen Jacobs said.

The highest bidder is sure to get a kick out of it and so will some of the people who have had it the toughest this year.

"We're hoping to raise some good money and give back to Nourish," Harris said.

Nourish is a registered charity that gives food to school children and their families across Wellington at Christmas.

"This year we've been asked to provide 1780 hampers," Nourish co-founder Claire Turner said.

"Each hamper is valued at about $150 and each family gets two boxes."

That's just over a quarter of a million dollars worth of donations. The demand this year is the highest it's been.

"We're around $25,000 short on our shortfall so anything that gets us as close to that as possible, that would be great," Nourish co-founder Gabrielle Ralph added.

The auction is live now.

"I don't think there will be another chance in New Zealand to drive a shredder, you're not gonna get it again," Jacobs said.

Shredding a rust bucket to help bring some sparkle to Christmas for those in need.

Nourish's 150 volunteers will deliver the hampers on December 11. You can donate on their website
