Drone captures flying humanoid above Browns Bay

On December 6, 2018, a weird flying humanoid was caught over Auckland, New Zealand. What is it?

Scott C. Waring claims:

This UFO looks a lot like a giant flying whale. UFOs are not always in disk shape, but come in many other strange shaped that you may have never imagined could exist before. The object is flooding long ways, and rotates a little bit. So I am wondering if this UFO was searching for something or someone? I only wish the drone had flown closer to the UFO rather than just recording it from a distance.

Eyewitness states:

I saw this over Browns Bay, Auckland, New Zealand on 6 December 2018. It was traveling about 5 to 10,000 feet up, moving across the sky from the east, in a northerly direction. I lowered the camera for about 3 seconds while keeping my eye on the object. Before I could raise the camera again, the object disappeared. I have included slow motion, close-up views of the object in the video at 200 percent and 400 percent magnification.
