This is New Zealand hip hop group Organized Rhyme. (Unrelated to the early 90s Tom Green project.) I found this on YouTube while browsing around for, of all things, New Zealand rap. (Hey, I was just curious.)
This track, “We Bak”, is actually pretty good. The production is really cheesy but I enjoy their flows a lot, and man that hook is great. They have a couple of other videos and they’re worth checking out but I think this one is probably the strongest.
