Te Wairepo / York Stream[1] is a major tributary of the Maitai / Mahitahi River in Nelson, New Zealand.
The Maori name "Te Wairepo" means "water running through a swamp". Before the valley was drained and houses built by early European settlers, stands of flax covered the low-lying areas through which Te Wairepo flowed.
Restoration of this, now largely urban, waterway has been a major focus of Project Maitai / Mahitahi, a Nelson City Council initiative to improve the health of the Maitai River and all its tributaries.
