Post pics of your Kona..

It seems to me to be dependent on the market you're in.

Mine was manufactured in SK in April 2021 and is sold here in Aus as a 2021 model. I bought it about a month after it was made.

 

Also the face-lifted model is designated as Kona Electric Series II here, so there are the dimple faced 2021s, and Series II 2021s on the road here.

 

Interesting. Odd, but interesting.

 

As I understand it, it's the result of a law which I gather the motor trade association managed to get through while no-one was looking which identifies a new car model year by the year first registered in NZ rather than when it was manufactured or what the VIN identifies it as. I think it came about because new cars can take a months to get here and then may sit on either the importers or dealer's lot for a long time. I once bought a Suzuki SUV 'new' in Dec 2013 that I found out later was built July 2011. My Kona identifies as 2019 by the VIN but legally is a 2018 model.
We cannot have 2022 Konas until 1st Jan 2022.
