Hi I am considering buying a phone from overseas but unsure whether it will work in NZ network(s)

The phone has 2 models for different network i guess:

Model 1:
4g: FDD-LTE, TDD-LTE, 3g: WCDMA, 2g:GSM

Model 2:
4g: TDD-LTE, 3g: TD-SCDMA, 2g: GSM


All discussions and publications in NZ mentioned only LTE but did not elaborate whether it is FDD or TDD. I bet it would be FDD seeing it's operating at 1800/700MHZ. Am I right?

Any advice is appreciated. Thanks~
