Is Cook Islands Māori the Same as Te Reo Māori?

Kia orana! If you’ve ever wondered whether Cook Islands Māori and Te Reo Māori are the same language, you’re not alone. It’s one of the most common questions we hear at Pacific Learners, and the answer is both fascinating and important for anyone who loves Pacific languages and culture.

The short answer is: they are related, but they are not the same language.

A Shared Ancestry

Both Cook Islands Māori and Te Reo Māori belong to the same language family. Cook Islands Māori is an Eastern Polynesian language belonging to the same language family as New Zealand Māori, Hawaiian and Tahitian. Think of them like cousins, they share the same ancestors and have many similarities, but centuries of separation across the Pacific Ocean have shaped them into two distinct languages with their own unique words, sounds and expressions.

What is Cook Islands Māori?

Cook Islands Māori is an Eastern Polynesian language that is the official language of the Cook Islands. It is closely related to, but distinct from, New Zealand Māori.

Cook Islanders often refer to their language as Te Reo Ipukarea, which literally translates to “the language of the Ancestral Homeland.” It is also commonly known as Rarotongan, named after Rarotonga, the capital island of the Cook Islands.

It is estimated that approximately 42,700 people speak Cook Islands Māori, including Cook Islanders on the islands of Aitutaki, Atiu, Mangaia, Mitiaro and Mauke, with each island having its own distinct accent and some unique words.

What is Te Reo Māori?

Te Reo Māori, often simply called Te Reo, is the indigenous language of the Māori people of Aotearoa New Zealand. It is one of New Zealand’s three official languages alongside English and New Zealand Sign Language. Te Reo Māori has experienced a powerful revitalisation movement in Aotearoa, with kōhanga reo (language nests), kura kaupapa (Māori immersion schools) and a growing number of New Zealanders committed to learning and speaking the language every day.

Key Similarities

Because they share the same Eastern Polynesian roots, Cook Islands Māori and Te Reo Māori have some beautiful similarities:

• Vowel sounds — the vowels in Cook Islands Māori are pronounced the same as many other Pacific languages, including New Zealand Māori.
• Shared words — many everyday words look and sound very similar across both languages
• Grammar structure — both languages share similar sentence patterns
• Written signs — both languages use the macron (to lengthen vowel sounds) and the glottal stop (to create a short pause in pronunciation)

Key Differences

Despite their similarities, Cook Islands Māori and Te Reo Māori are distinct languages. A speaker of one would not automatically understand the other, though they may recognise familiar words and patterns. The vocabulary, pronunciation and expressions have developed separately over many generations, shaped by the unique geography, culture and history of each island nation.

Cook Islands Māori is related to, but different from, the Māori language spoken in Aotearoa New Zealand.

Additionally, there are several distinct dialects within the Cook Islands themselves, including Mangaia, Rarotonga, Ngāpūtoru, Aitutaki, Manihiki, Rakahanga, Tongareva and Pukapuka, with Rarotongan being the main dialect taught as it is the dialect of the capital island.

Cook Islands Māori Language Week in New Zealand

Every year, Aotearoa New Zealand celebrates Cook Islands Māori Language Week, known as Epetoma o Te Reo Māori Kūki ‘Airani. In 2026, Cook Islands Māori Language Week runs from Sunday 2 August to Saturday 8 August. This is a wonderful opportunity for Cook Island communities, schools and families across New Zealand to celebrate, speak and share their beautiful language with pride.
