Following on from the bestselling Te Reo Kapekape (2023) and He Iti te Kupu (2021), Hona Black's new book - co-authored with Te Aorangi Murphy-Fell - is an essential reference for any Maori learner or speaker. Surging interest in te reo Maori in recent years has led to a range of errors becoming common in classrooms and everyday use, many caused by language interference (following the patterns of English rather than te reo). This book sets out to correct that trend with easy-to-follow, fun examples of language errors. In six chapters focusing on different types of mistakes, the book directs readers to correct usages, numerous examples, and detailed explanations in both te reo and English. Nga Hapa Reo is a stimulating read for anyone wanting to improve their command of te reo Maori, whether language learner or fluent speaker.
