Trig M

Out and back

Once you reach the summit—marked by the classic wooden trig point—the full scale of the Canterbury wilderness is revealed. To the west and north, the rugged, often snow-dusted peaks of the Torlesse, Big Ben, and Craigieburn Ranges stretch into the distance, looking like a jagged spine across the South Island. On a truly clear day, the view to the east is just as impressive. You can see right across the vast, checkered patchwork of the Canterbury Plains, past Christchurch City, all the way to the sparkling horizon of the Pacific Ocean.

Standing at the trig, there is a distinct "top of the world" feeling. The summit area is spacious enough to find a private patch of grass to sit down, crack open your thermos, and enjoy a well-deserved snack while soaking in the 360-degree scenery. It’s the perfect spot for that "summit hero" photo before you begin the trek back down.

Getting There

Trig M is easily accessible from State Highway 73 (The Great Alpine Highway), making it a perfect stop if you are travelling between Christchurch and the West Coast.

From Christchurch, head west towards the mountains. You’ll pass through the small town of Springfield and begin the climb up over Porters Pass. Once you reach the summit of the pass and pass the lookout, keep a very sharp eye out. The Starvation Gully car park is a small, unassuming layby on the left-hand side of the road, just a few minutes past the lookout and shortly before you reach Lake Lyndon.

Be careful—if you find yourself driving alongside the shore of Lake Lyndon, you’ve gone slightly too far! There isn't a massive "Trig M" highway sign; instead, look for a small marker pole and a map board near the fence line at the edge of the gravel pull-off.

Wildlife Spotting

The high country is home to some of New Zealand’s most iconic avian residents. As you move through the lower shrublands, keep your ears open for the friendly "cheep" of the Fantail (Pīwakawaka) or the delicate, trilling song of the Grey Warbler (Riroriro). You’re also likely to see Silvereyes flitting through the bushes and the occasional Paradise Shelduck flying overhead.

However, the real treats are the alpine specialists. Keep an eye on the rocky outcrops and the sky above the ridges for the New Zealand Falcon (Kārearea). These are our fastest birds of prey, and seeing one dive or soar over the tussocks is a rare and thrilling sight.

You might also get a visit from the world’s only alpine parrot, the Kea. While they are more common further into the Craigieburn Range, they are known to frequent the Trig M area. If you do see one, remember to keep your belongings close—they are famously inquisitive (and mischievous) and have a particular fondness for rubber windscreen wipers and backpack straps!

Seasonal Magic & Practical Tips

Trig M is a fantastic year-round destination, but each season brings its own flavour:

• Summer: Long daylight hours and golden grass. It can get very hot on the exposed ridges, so start early (around 8:00 am or 9:00 am) to beat the midday heat.
• Autumn: Often brings the most stable weather and incredibly clear, crisp air, making for the best long-distance views to the coast.
• Winter: The trail often sees a dusting of snow. It transforms into a winter wonderland, but you’ll need sturdy boots and potentially gaiters. Check the weather forecast for ice and wind chill.
• Spring: You’ll see the fresh green shoots emerging through the tussock and often a dramatic backdrop of heavily snow-capped peaks in the distance.

• Layer Up: Even on a warm day, the wind at the trig can be biting. Pack a windproof jacket and a warm hat.
• Sun Protection: There is almost no shade on this track. Even in winter, the alpine sun is fierce. Bring a hat, sunglasses, and plenty of sunscreen.
• Water: There are no water sources along the trail. Ensure you carry at least 1.5 to 2 litres per person.
• Check the Wind: The Selwyn high country is notorious for strong North-West winds. If a "nor'wester" is howling, the ridges can be very exposed and unpleasant. Check the mountain forecast before you head out.

Local & Regional Context

The area you are walking through is part of the Korowai/Torlesse Tussocklands Park. The name Korowai is Māori for "cloak," and it’s a beautiful metaphor for the way the golden tussock covers these mountains like a protective garment. This land holds significant cultural value to Ngāi Tahu, who traditionally used the mountain passes as seasonal travel routes (ara tawhito) to reach the West Coast for pounamu (greenstone).

Geologically, the Torlesse Range is part of the "greywacke" backbone of the South Island. The landscape here is a testament to the power of uplift and erosion. The tussocklands themselves are a vital ecosystem, providing a home for rare lizards, insects, and birds that are specially adapted to the harsh, high-altitude environment. By sticking to the marked track, you’re helping to protect these fragile plants from being crushed.

After the Walk

After 425 metres of climbing, you’ll likely have worked up a significant appetite. Fortunately, the town of Springfield, just 22km back towards Christchurch, is a haven for hungry hikers.

• The Springfield Hotel: This is your classic kiwi country pub. It’s got a great atmosphere, cold beer on tap, and a menu full of hearty pub classics. It’s the perfect place to sit by the fire in winter or on the porch in summer and swap stories about your hike.
• Taste of Kiwi: A lovely local cafe that specialises in fresh baking and great breakfasts. If you’re after a big brunch or a slice of homemade cake, this is the spot.
• Yello Shack: Renowned among the hiking community for having some of the best coffee and pies in the region. Their outdoor seating area is a great place to relax and soak up the last of the mountain air before the drive back to the city.
