Hi again...
A Walter SMITH, Master Mariner was naturalised in 1891.
NZ Gazette - p.530

Archives NZ in Wellington should hold a copy of his Certificate of Citizenship. This isn't all that helpful as it just mentions his name and the fact that he is now one of us.
What's of interest is that to apply for citizenship he had to submit an
"application for naturalisation, usually giving name, age, birthplace, residence, occupation and length of residence in New Zealand. The application was considered by government officials and ratified by the minister."Archives New Zealand Research Guides - Citizenship

A copy of his Certificate of Citizenship should be easy enough to obtain but, more importantly, looking for his Certificate of Citizenship will tell you whether or not his application for naturalisation still exists.
The first step is to view the following index held at Wellington Archives. This will hopefully point to both the certificate and the application....

It would be really handy if Mary applied for naturalisation before she married Walter. Her application for naturalisation would hold a lot of info as yet unknown.
I know that when a husband was naturalised his wife was did not have to apply as she was automatically given citizenship. But as Walter was naturalised in 1891 and the marriage wasn't until 1892 I'm not sure if Mary needed to apply separately, assuming she wanted citizenship.
Hopefully some can advise.
I guess the first step is to check ancestry for naturalisation applications for a Mary PETERSON pre-1892 and a Mary SMITH post-1892.
