Hi @Anna18927
Not in NZ, but here's my input ...
Great advice from @Guy991
I would consider buying in bulk if something affordable was available for my region, not my country. This would address his concern about repetitiveness, and would make the content more relevant.
As an example, most of what we can get here, comes in packaging that features a lion or a rhino or a giraffe. That covers most of sub-Saharan Africa, but has little relevance to my region. It's not a way for me to help guests experience my specific location. Instead, it's a general theme showcasing what they've already seen on their way down here, or will see later.
