Ko Wiriwiri rāua ko Kina is a bilingual storybook app for children developed by the Ministry of Education New Zealand. The app tells the story of two young children, Wiriwiri (age 7) and Kina (age 9), who attend school together and learn to write their first words in Māori language. The story is set in Rangihoua in Pēwhairangi during the year 1816 and features the Ngāti Torehina and Ngāpuhi tribes.

The app is available on Android and includes narration and text in both Māori and English languages. The user interface is easy to use and the story is accompanied by colorful illustrations that engage children. However, the app lacks interactive features, which may make it less appealing to some children. Overall, Ko Wiriwiri rāua ko Kina is a great educational tool for parents and teachers looking to introduce children to Māori language and culture in a fun and engaging way.
