It's 7:22 pm Monday 23 May. I'm in you're future XD
If the game doesn't come out by GMT+1 UK time 12:30 pm Tuesday 24 May, which will be 11:30 pm at night on Tuesday 24 May for NZ, I have another game that releases first thing tomorrow. It's Overwatch for Xbox One. Retailers will start and are allowed to, start selling it when they open tomorrow, as it's scheduled to release "24 May", regardless if it's not 24 May in other countries. But I'd say NZ/Australians would appreciate it if Planet Coaster Alpha 2 came out on "Tuesday 22 May" our time. Even if it's like 11:50 pm at night or something.
But then again if they don't manage to, it's not the end of the world. I will do a YouTube video of it, if it comes out before 1pm UK time, otherwise it will be during Wednesday afternoon NZ/Australian time when I get home. There is little time difference between NZ and Australia. I have a Hauppauge HD PVR2 which I use to share Xbox gameplays with friends etc and can use it to record PC games too. I also have AMD Raptr too.
