28/08/2026: ARAPUNI DAM CLOSURE – IMPORTANT TRAIL UPDATE
From 9am Tuesday, 1 September 2026, Arapuni Road across Arapuni Dam will close for approximately 24–36 months while repair and enhancement works are carried out by Mercury.
This closure will affect trail users travelling between Arapuni and Waipapa Dam.
🚫 The Powerhouse Road detour is for vehicles only – trail users cannot walk or cycle along this detour.
This means trail users travelling between Arapuni and Waipapa Dam will need vehicle support to travel around the closure.
If you are planning to ride or walk this section of the Waikato River Trails, please plan ahead and make arrangements for transport around the closure before starting your journey.
We will have signage in place at trail entry points to help ensure trail users are aware of the closure.

The Mangakino Lakefront Reserve is the starting point for the Waipapa Trail, before making your way up Lake Road to the beginning of the trail at the forest edge.
