I'm a huge fan of the original British TM, but TM New Zealand is honestly amazing. The whole thing is available on YouTube (thanks Little Alex Horne + team!!!).
In my and many of my friends' opinion, TM New Zealand Series 2 is one of the best TM series. TM New Zealand in general is absolutely unhinged.
Series 1 feels a bit off, which is probably because it's unlike British TM. I got used to it fairly quick though.
TM NZ Series 3 (final episode releases on YouTube in 2-3 days)
Yep! Series 4 hasn't "released" on YouTube yet. I saw Paul William's story on instagram that they're releasing Series 5 on TV, but sadly I don't have access to that. I'm fine being behind by 1-2 years though.
