If you can provide all the required evidence for the culturally arranged marriage visa (see here
https://www.immigration.govt.nz/new-...=residence-IND), this is a good route for your new spouse to follow - you are then applying in a much smaller category, with more clearly defined requirements, than the partner-sponsored visitor visa. The partner-sponsored visitor visa requires evidence of a couple living together in a shared home over a connected period of time, which if one party who normally lives in NZ is travelling to India for the wedding is not likely to be possible to provide, whereas the culturally arranged marriage visa allows the newly married person to come to NZ to fulfil the living-together criterion, and then apply for the next visa from within the country.
I suggest you look at the INZ factsheets for both the visas, to understand the requirements, then you'll be in a better position to decide what best fits your circumstances.
