Hi Cam123. I've got the same car. I checked my Owner's Manual and was surprised to see that the normal maintenance schedule listed for our cars (1.6L T-GDI SR petrol turbo) only goes to 96 months or 80,000 km.
In the same section of the manual (7), I noticed that the service schedule for the 2018 petrol 2.0L GDI also goes to 96 months but 120,000 km.
If it was me, I'd be ringing Hyundai NZ and speaking to their technical department (and asking nicely if they would email you their 100K service requirements). I won't have to worry as after 6 years ownership I've only got about 11,000km on the clock.
Sorry I haven't got any more helpful news for you.
