I didn't see this mentioned in the threads, but I could be mistaken.
Strangely since the article was published, he "had to remove the Mongrel Mob from the mod due to legal issues and community outcry"

"Step Inside Grand Theft Auto New Zealand
Los Santos now comes with the Mongrel Mob and Pak ‘n Save.
Kiwi GTA V fans will feel at home in Los Santos thanks to Dre Hema-Kani, who uploaded his mods to Reddit earlier this week. Using a PC and Photoshop, the New Zealand–based father-of-two slipped local brands onto billboards and storefronts—and added a few familiar thugs. The Creators Project called Dre to find out more.
The Creators Project: Why did you choose NZ mods?
Dre Hema-Kani: I pretty much wanted to turn the game into somewhere that reminded me of home. Driving around, seeing familiar things. It was more for myself than anyone else, but I’ve had heaps more interest than I expected. I only put it on Reddit to see if my gaming friends were into it, and if people in New Zealand would actually download it.
The Creators Project:Are these the first treatments you’ve done?
Dre Hema-Kani: Yes, they are something I always wanted to do but I never had the time. I had two weeks off from work so thought I’d learn. After a week I uploaded them to see if I should carry on, and it turns out I should.
The Creators Project:What's your day job?
Dre Hema-Kani: I work at a slaughter board, full-time.
The Creators Project:Tell us more about the mods.
Dre Hema-Kani: I made different trucks and trailers that represent the companies from around here. Pak 'n Save, Supercheap Auto, mainly New Zealand companies, but I’ve got bigger brands that you usually see driving around a New Zealand city. Because GTAV has gangs, I made the gangs New Zealand. I’m working on changing the emergency departments to New Zealand ones. I’ve done an Air New Zealand jet, so when I do my first upload that will be on there."
