"New Zealand citizens and permanent residents who meet
the criteria to be ‘ordinarily resident’ can buy property
without restrictions.
Overseas people cannot buy a house or land in New Zealand.
If you have a residence class visa but you are not yet ‘ordinarily
resident’, you can buy or build one home to live in if you get consent
from the Overseas Investment Office. You must be committed to living
in New Zealand for the long-term.
There are different consent requirements depending on what type of
land you are buying.
There are different rules for Australian and Singaporean citizens and
permanent residents under free trade agreements."
