Strange sighting on Takapuna beach on 6th November [Auckland NZ]

First off, sorry for the atrocious video quality. It was really hard to get anything in focus with my phone, and I just compiled the best captures I could get.

Anyway, I was with two friends on a beach late at night when we saw these orbs appearing and disappearing for over an hour. Near the end, three orbs showed up at the exact same moment in a straight line and vanished at the same time. Really wish I'd filmed that one.

What makes this even stranger is that two years and three days earlier, I saw the exact same thing in the same part of the sky, seemingly lined up with the same two stars (I Hya and G Hya, if my star app is actually accurate). I filmed that one too, although the quality was even worse.

I'm kinda embarrassed to post this because of the shit video quality, and I'm sure Reddit's compression will butcher it even more, but fuck it. If anyone has an explanation for what this might be, or any questions, that'd be cool. We saw at least 100 of these orbs that night, all with different brightness and duration.

Lastly I tried to post this shit on r/ufos twice but was removed by mods.
