Yeah it is mostly Sundays in NZ that's true. For pilots there are however at least two regular evenings in Aussie, Monday milk-runs are a favourite of mine (usually between Sydney and Melbourne) and are always busy. Other than that you can catch some great ATC coverage in Europe and North America (USA mostly) on the weekends, and lots of Asian coverage during the week evenings out time. Only prob with the overseas flying is you really need to learn on your feet, and quickly, re local procedures, geography etc.
Sounds like you're interested in controlling tho Zain and for that you will begin your training in NZ (if that's where you want to control). From what I understand you manage Ground (GND) positions initially then move on up with training to other positions, Deliveries, Tower, Approach etc. Once you are underway you can be online any time that suits you, it's a waiting game then to see who takes the bait and comes to fly in/out of your location.
You will need some patience grasshopper
