How did Immigration New Zealand come up with the criteria for the documents required? No doubt policymakers in Wellington sat around brainstorming about the types of documents a couple could usually provide. Naturally they reflected on what documents they personally could get to prove their own relationships. It’s sometimes said that the law reflects the makers; that is certainly true in this case. Unfortunately, whoever designed the rules didn’t realise they were dealing with people who come from countries that don’t operate the same as ours. Hence they failed to give immigration officers appropriate guidance as to what to do when not presented with typical documents as prescribed by the rules.
