Actually they did consider whether to make it terrestrial only. But they found that it would be sub-optimal - the shorter wavelength UHF signal required for digital does not propagate as far as the VHF signals. There will always be areas of NZ that just can't be viably covered by terrestrial signals due to its hilliness. Satellite always works as long as you can see the right area of the sky. Believe me they wouldn't have spent all the money having two different broadcast systems if they didn't think it necessary.

It was decided also that they couldn't do just satellite as this would require everyone to get a satellite dish where as an aerial -> aerial upgrade path makes more sense and it is more likely that manufacturers would integrated DVB-T into their televisions.

And they didn't go MPEG-4 from the beginning for satellite because people had already bought DVB-S boxes because TVNZ had been broadcasting one and 2 for some time over MPEG-2.
