The video ends as the wheelchairs appear to be uncoupled while the users inspect their various modes of transport.
The footage was shot from a nearby bus stop, and prompted the smartphone user to observe "only in Whangarei!"
Ms Tangey said she was waiting for her bus on June 14 between 2.30pm and 3pm when she saw the peculiar action unfold.
She saw the mobility scooter, then the wheelchairs and thought "oh my god I so have to video this."
The 18-year-old said she hadn't seen them before, and hasn't seen them again since.
"I actually thought it was dangerous but then I laughed about it. I wasn't expecting to see something like that."
Her video has been shared almost 1000 times and she said she was definitely not expecting her video to be so popular.
Inspector Wayne Ewers said it was "not the wisest thing to be doing".
"Especially travelling down the centre with traffic going past on both sides."
He said it was people not thinking of their own safety first.
"They would be best to go to the nearest pedestrian crossing or set of lights and cross safely."
Tiaho Trust chief executive Jonny Wilkinson said he understands the three people in the video are local residents from around Tikipunga who regularly travel in such fashion.
"They are genuine wheechair users and sometimes one needs to cross the road to get to the other side!"
"I think the facebook video takes it out of context somewhat."
