If you saw a moving trampoline along Auckland's northern motorway on Sunday, you're not alone.

A car was spotted driving down an Auckland motorway with a trampoline bouncing on its roof, held in place only by two pieces of rope fed through the car's windows.

Professional furniture mover Brad Jackson saw the astounding sight, and as someone who knows a thing or two about moving things, said he couldn't believe his eyes.

The trampoline was considerably wider than the car, and was bouncing up and down in the wind.

KIWI AZ BRO/FACEBOOK The swingset move that caught the attention of police and the nation.

Jackson was himself moving furniture when he spotted the car heading south on Auckland's northern motorway on Sunday afternoon.

As he approached the moving trampoline he needed to slow down to get a better look.



"I couldn't believe it when I saw it... it was hanging over the side of the car. I've seen beds on [car] roofs but not that wide, nothing like this," Jackson said.



He said it appeared that two bits of rope tied around the trampoline and through the door windows were holding on "for dear life".



"[The driver] wasn't going slow, every time she sped off and then stopped it was bouncing up. And she wouldn't have been able to get out of her car because the doors were tied shut to hold it down.



"Everyone was slowing down to check it out."

SUPPLIED A Hamilton man was stopped with three sofa chairs tied onto his car with string.

Jackson said it was "easily" in the top five most bizarre furniture moves he'd seen.



Police have been approached for comment.

This hasn't been the first time people had taken unorthodox methods to transport inconvenient household goods.



In south Auckland last year a driver was fined for attempting to transport a backyard swingset on top of their people mover.

The attempted move was posted on Facebook, showing the swingset straddling the van as half the equipment hung outside the vehicle.

In 2015, a Hamilton man was pulled over after police saw him transporting three sofa chairs tied with string to the roof and boot of his car.

His excuse to police was, "My wife wanted them gone".
