If you're looking for a unique way to decorate your house for Christmas, Treezilla may be it.

The Godzilla-shaped Christmas tree is the work of Rotorua-based pilot Steven Newland, who has put his creation up for auction on Trade Me.

The 1.8 metre tree breathes smoke, has plastic teeth, paper talons and eyes that glow red.

Steven says friendly competition between him and a neighbour has lead to a yearly tradition of unique festive decorations.

"At the time, we did a time portal Christmas tree, so half of it went down out of the floor and the other half popped out of the ceiling upside down.

"After we did it our neighbours stopped playing with us but since then we do a random Christmas tree each year."

In 2017, Steven put together a pac-man themed tree.

Treezilla was created for Christmas 2018.

It was made from four large Christmas trees, chicken wire, a smoke machine and LED lights.

"I gave myself a month to build it, thinking it would take a while, but I had it finished in two weeks,"

Steven didn't want to say how much the Treezilla cost to build but he hoped he would be able to recoup some of the costs to go towards his next creation.

Any extra money will be donated to CanTeen, says Steven.

The unveiling of each year's Christmas tree had become an event for Newland's friends.

"Everyone finds it a great laugh. A lot of my friends get quite excited to see what tree I will do next, they send suggestions on what I can do.

"It's gotten to the point where you have to live up to expectations each year."

Trade Me spokesperson Millie Silvester says the tree was a piece of Kiwi ingenuity.

"Over the years we've seen tonnes of listings for Christmas trees and decorations but never a smoke-breathing Godzilla Christmas tree."

In the last seven days there had been 60,000 searches for Christmas trees on the site.

"There's currently 450 Christmas trees on site but nothing quite like this," says Millie.

The Treezilla auction on Trade Me had a reserve of $250 and closed on November 27.
