1. Addressee line - The recipient's name and any appropriate titles go here. 
2. House number and street name - The house number and street name are listed in this order, without commas between them.
3. Dependent locality - On a line by itself, include the dependent locality, if applicable.
4. Locality and postal code - The locality, followed immediately by the postal code, goes on this line without any separating punctuation.
5. COUNTRY - NZL, in all caps, goes on the final line.
