I am half South African and half Nigeria, but my dad is south African and i am traveling to New Zealand with south Africa passport, can i fly from Nigeria ?? because my mom is buying me ticket from Nigeria, what questions do immigration ask people holding visa waiver passport to new zealand at the airport ??

If you hold a South African passport, no visa for entry into NZ is required. You can fly directly from Nigeria.
