The Maraetai Trail

19/09/2025 – We have received the following update from Mercury regarding the Whakamaru Dam and upcoming closures. This information is also shared on our social media.

Whakamaru Division Gate – Seven Year Dry Test

Mercury’s Dam Safety Project ‘Dry Test the Diversion Gate’ at Whakamaru Power Station will be happening during October and November, which requires a full road closure. We will be inserting 16 stoplogs (long steel beams) that are stacked on top of each other. They are dropped into pre-prepared slots which are designed to hold back large volumes of water. The crane on site hangs over the 2nd lane, which makes it impossible for cars to cross, and too dangerous for cyclists to cycle past. This will take place on:

* 13th – 17th October 2025, from 8am to 7pm daily.

* 17th – 21st November 2025, from 8am to 7pm daily.

This piece of work is a crucial part of Mercury’s dam safety obligations and is necessary to ensure the gate’s ability to function as it was designed to. During a flood we need to ensure the water flowing through is accurately controlled. The testing ensures it is reliable, and has the ability to perform when it is needed the most. The Diversion Gate is a crucial piece of equipment for protecting infrastructure and property and the environment from flood related incidents.

There is an alternative route, SH32 – Poihipi Road – Tirohanga Road to SH 1, which adds another 40kms (30 mins) to your trip if you are heading into Tokoroa by car.

The rustic The Dam Village Bakery Café is the ideal spot to grab a coffee and a scone, or an All-Day Breakfast before starting the Maraetai Trail that begins adjacent to the Whakamaru Dam. As you head through the grounds of the Whakamaru switching station, the trail gently winds high above the river through a pine tree lined pathway next to farmland as sheep and stock graze.

The Trail!

The rustic Dam Village Bakery Café is the ideal spot to grab a coffee and a scone, or an All-Day Breakfast before starting the Maraetai Trail that begins adjacent to the Whakamaru Dam. As you head through the grounds of the Whakamaru switching station, the trail gently winds high above the river through a pine tree lined pathway next to farmland as sheep and stock graze. As the trail gradually descends, and you head deeper into forest and farmland, you’ll enjoy spectacular views of the river, rolling hills and landscape along the way. The trail is surrounded with native Totara and Manuka and alive with the sounds of birdsong and nature, as it winds its way toward the magnificent Mangakino Suspension Bridge which is the mid-way point between Whakamaru and Mangakino. The 70-metre-long suspension bridge hangs 12 metres above the river, providing stunning views of the river and forest. Continue following the forest trail as it descends to river level, and stop for a rest to capture the moment in the photographic viewing frame on the water’s edge at Lake Maraetai – one of the deepest of the seven man-made lakes on the Waikato River. The next section follows the lake edge through a pathway and boardwalk sections that are lush with thousands of native trees.

As you near the end of the trail you’ll enter the tranquil town of Mangakino via a pathway through the Mangakino Golf Club, a 9-hole course with picturesque views of Lake Maraetai and the surrounding forests. The trail ends at the Mangakino Lakefront Reserve. Stop and enjoy the laid-back atmosphere while you watch the power boats, wakeboarders and waterskiers racing across the lake. While you’re in Mangakino Village, take a stroll around the township that has no traffic and no traffic lights, and enjoy a bite to eat and a refreshment at the local cafes and restaurants. And if you’re looking for something a little different to do, play a round of Disc Golf at the Mangakino Disc Golf Course – where instead of a ball and clubs, players throw a plastic disc (or “Frisbee”) into a standing metal basket. It’s fun for everyone and you can rent discs from the local Four Square in Mangakino.
