Have trouble with your a's and your o's. Confused with tōku and tāku? Do I need to use i or ki? If you would like to learn more about grammar then this book could be a good self study guide. 

David Kārena - Holmes has a background in learning Italian and studying Linguistics. Married to a native speaker, his own te reo journey led to him working as a tutor at Otago Polytechnic where he became interested in the grammar of Māori. This book is an outcome of that journey. A resident in Whakatū (Nelson) for several years (where he wrote a successful series of te reo Grammar articles for the Nelson Mail) he has recently returned to Otakou.

The title of this pukapuka Te Reo Māori- the basics explained says it all really.

It is a look at the basic ways that phrases and sentences are constructed (syntax) while also unpicking the morphology of words- how words are formed. It is well set out, with well sign posted sections, and rather than being a text book that you study from cover to cover, operates as a text which you can dip in and out of in the quest to conquer the challenges of learning about possessives, verb and noun phrases, determiners and particles.

This book will help. It may clear some issues up for you. It may act as a springboard for learning more.

There are some copies floating about in various parts of the Health school throughout the motu- so ask someone in the TKW at your site if they have a copy that they could share with you.
