Hi K
We can't look up census records in NZ sadly, all destroyed
Electoral rolls are on CD's 1881, 1893 and coming later in the year 1896
What was Alice's birthdate? age when she married.
Do you have her parents? we may find more info on her if we know her parents.
Street Directories are available for lookups in lots of libraries, that way you can find where they lived etc occupations.
Later Electoral rolls are also in some libraries, but are not indexed so you need to know the areas they lived.
Bye
Althea

On the marriage index Alice's surname has been recorded as FERGESS, a not uncommon problem sadly.
Do you have all their death info?
