The Cook Islands is a self-governing territory in free association with New Zealand, located in the South Pacific Ocean. Comprising 14 islands, it is divided into two groups: the Northern Group and the Southern Group, with Rarotonga being the most populous and the capital. 

The islands are known for their stunning natural beauty, including pristine beaches, turquoise lagoons, and lush tropical landscapes. It has a tropical climate and is a popular destination for tourists seeking a serene, tropical escape.

People within the country write address formats differently. In rural and less populated areas, formal street addresses may not exist or may be incomplete, leading to the reliance on P.O. Box numbers or specific local landmarks instead of detailed street names. This informal address format is due to the sparse infrastructure and the way local communities are organized.

Additionally, the Cook Islands’ connection with New Zealand influences its address formatting, as it adheres to a simplified postal system for both domestic and international mail. In many cases, addresses in the Cook Islands prioritize the P.O. Box number rather than street names, which can make navigation more challenging due to the lack of comprehensive urban planning.

Moreover, there are different types of addresses, each with its specific element requirements. If you need to mail a client or customer in the Cook Islands but are unsure of the correct address format, we can assist you. We have listed all the different types of addresses, along with their formats and examples.

Recipient Name

In the first line, write the recipient’s full name. If you are sending the mail to a business, the company name will appear in the first line. Write the person’s name and department in the second and third lines. Add ATTN. in front of the person’s name to ensure the internal mail distribution system sends the mail to the correct office and desk.

Street Address and Locality Name

In the second line, write the building number followed by the street name of the residential or business address. If the recipient uses a P.O. box, write “P.O. BOX” followed by the box number. P.O. Boxes are preferred over street addresses; hence, we recommend writing them in the second line.

Island Name

Write the name of the island where the person lives. Some of the major islands in the Cook Islands are Rarotonga, Aitutaki, Mangaia, and Manuae.

Country Name

Write the name of the country in the last line. When sending international mail to the Cook Islands, write the country’s name in capital letters.

Residential Address Format

Write the recipient’s name, street address, P.O. box number, island, and country name.

Rural Address Format

Typically, the streets in rural areas of the Cook Islands do not have a formal name. In this case, write the name of the village or the settlement, followed by the nearest larger town or city. Add the rest of the address elements in the same way as the residential address.

Business Address Format

Instead of the recipient’s name in the residential address, write the company’s name in the first line. Write the person’s name in the second line, and add their department in the third line.

International Address Format for NGOs and Organizations

Write the organization’s name in the first line and the specific department in the second line. Place all the other address components, except the recipient’s name, in the same way as the residential address.

P.O. Box Address Format

Instead of the street address, write the term “P.O. box” and then the box number in the residential address.

Government Office Address Format

Instead of the recipient’s name, write the office and department names in the residential address on the first and second lines.

Address Format for Multiple Recipients

If you want to mail multiple people in the same household or business, you should write each name on a separate line of the residential and business addresses.

Address Format for Courier Services

If you send mail using courier services like DHL or FedEx, add the recipient’s contact details to the end of the residential address. Delivery agents can call them if they cannot find the address.
