UFO napier (NZ) 2019 11 22

I was talking to my brother the other day, anyways he mentioned he saw a UFO about a year ago, which he can't explain and freaked him TBH
He did make a thread on reddit at the time

Heres a slightly better quality mp4 (still not good)

like he saiz in his post he was watching it for more than 10 minutes,
I would guess some sort of balloon
It also could be a satellite but it seems too bright (sure the ISS can be as bright or brighter but is not visible as long) and satellite flares (eg iridium) also flare brighter but normally only once before quickly dying out. Rocket lab does have their launch site nearby but AFAIKS no launches happened that week. Starlink was doing launches around then but I thought those were lines of satelittes?

Any better guesses?
