With further inspection, the cyclist is also wearing a sign saying "stoat", - a short-tailed weasel, clarifying the bizarre costume.
"I was just going to get some coffee during work and I saw him about to cross the road at the light," Pigman told the Herald.
"He looked in control etc and it looked hilarious - hence why I recorded it."
Pigman seems to be a bit confused about the whole ordeal saying "What?" as the cyclist rides passed her.
This hilarious footage comes after another cyclist was spotted down the same street wearing a box over himself.
"I'd seen the videos of the guy with the box and it reminded me of that immediately, except that this was a giant stoat," Pigman laughed.
"I was keen to see if anyone else had seen it too hence why I posted on Vic Deals. It's such a Wellington thing to have happen!"

Kiwis on Pigman's video were getting excited that a "bike challenge" may be brewing in Wellington.
"Everyone's getting so creative these days.. First a box now an animal! I'm excited to see what tomorrow brings," one commented
Another chimed in saying: "I love when people try to one up the box biker."
"Now! Do not ride on the back of Bike Box Guy's fame," another joked.
The first cyclist was seen covered by a cardboard box that was the full length of the bike.
The genius cyclist has been spotted numerous times with the large box, sending Wellington social media users into a frenzy.

Wellingtonians joked, saying "Maybe I'll do this instead of finding a flat, looks much cheaper" and "when you can't afford public transport".
Others suggested the raincoat hack was "Kiwi ingenuity at its finest" while another person said "it's great to see the Onzo concept really taking off".
"Box man" spoke to Stuff on Wednesday revealing why he wore a box through the city.
"It was getting pretty late and I had to get back home to my kids but I had this giant box and I kinda wanted to take it home for the kids to play in, and it was raining," he said.
"I had no way of getting it back so I sort of looked at the box and I looked at my bike and I thought, whoa, they are the same size."
