Purchasing a Condo Insurance

When my family migrated to NZ or New Zealand, we decided to live in a condo unit near the city. My mom's work is in the city proper and if we live nearby then we can save transportation expenses. Currently, we are living in my Aunt's house in Auckland because we haven't move to our new condo. My mother has been contacting the homeowners' association and the condominium owner regarding our insurance, but to no avail. My mother doesn't know how and where to get our house insurance. We want to live in our new home but the problems with the house insurance keep us from living there.
