Mahau is a free mobile application that aims to help users learn the te reo Māori language. It is developed by wellingtoncitycouncilnz and is available for the Android platform. Mahau is designed to help users learn the dialects of Taranaki Whānui and Ngāti Toa Rangatira, the mana whenua iwi of Te Whanganui-a-Tara/Wellington.

One of the key features of Mahau is its synchronised narration in standard te reo Māori and the two dialects mentioned earlier. Users can choose to swipe to read or touch to hear the narration. Additionally, users can record their own narration and create their own pepeha. The app allows users to export pages, images, and audio to colleagues, friends or social media. Mahau also includes maps, animations, tutorials, and informative videos. The app has visually impaired functionality as well.

Mahau is produced by Kiwa Digital, a world-leading cultural services agency. Overall, Mahau is an excellent app for learning the te reo Māori language, especially for those who want to learn the dialects of Taranaki Whānui and Ngāti Toa Rangatira.
