Why Was Saint Arnaud's Name Changed?
The village was first called Rotoiti until 1921. It was renamed by the Department of Lands and Survey. This was done to avoid confusion with other places that had the same name.
Records show that from 1921 to 1951, both names were used. People living there and government groups used both names. A letter from 1950 explained the problem. Mail for Lake Rotoiti in the Nelson area often went to Lake Rotoiti near Rotorua.
Because of this mix-up, the name was changed to Saint Arnaud. However, the new name was not officially approved until July 19, 1951. Some local people did not like this change. A petition was sent in 1950 to stop it. Even today, some residents still use Lake Rotoiti as their address.
In 2007, there was a plan to change the name back to Rotoiti. Another idea was to use both names, which is common in New Zealand. A survey showed that about half of the residents wanted the original name back. But the plan did not go through.
The name Saint Arnaud can be tricky to say. The official way to say it is like the French name, which sounds like "ah-noh." But many locals say it differently, with the end sounding like "ah-nəd."

A water taxi service operates from a jetty at the northern end of Lake Rotoiti. There are also two campsites nearby, one at Kerr Bay and another at West Bay. A daily bus service connects Saint Arnaud to other towns. These include Nelson, Murchison, Greymouth, Blenheim, Westport, and Picton.

Exploring Nelson Lakes National Park
Saint Arnaud is a gateway to the Nelson Lakes National Park. The park has a Department of Conservation (DOC) Visitor Centre. Here, you can learn about the park's wildlife and how it is managed. The staff can give you advice on exploring the area.
There are many walking paths and nature trails. They are suitable for all skill levels. The DOC maintains these trails.
Saint Arnaud is the start of the challenging 80-kilometre Travers - Sabine tramping circuit. This trail follows the Travers River valley. It goes over the Travers Saddle, a high mountain pass. Then it goes down the Sabine River valley to Lake Rotoroa.
From Lake Rotoroa, hikers can return to Saint Arnaud. They can cross a low pass to Lake Rotoiti via the Speargrass Track. Or they can take a higher route over Mount Angelus. Another option is a water taxi from the DOC Sabine Hut on Lake Rotoroa to the northern end of the lake.
In winter, people enjoy snow sports at Rainbow Skifield. This ski area is on the eastern side of the Saint Arnaud Range. Other fun activities in the area include fishing, hunting, kayaking, sailing small boats, and gliding.
How to Get Around Saint Arnaud
State Highway 63 runs through Saint Arnaud. This highway connects the town to Blenheim and the Marlborough area in the east. It also links to Murchison and the West Coast in the west.
The Korere Tophouse Road leaves State Highway 63 a few kilometres east of Saint Arnaud. This road is the most direct way to get to Richmond and Nelson.
Network Tasman manages the electricity supply in Saint Arnaud. Electricity comes from Transpower's national grid. The power station is about 15 kilometres north of the town.
The Tasman District Council handles stormwater and wastewater systems in Saint Arnaud. However, individual homes need to set up their own fresh water supply.
Learning in Saint Arnaud
Lake Rotoiti School is the only school in Saint Arnaud. It teaches students from ages 5 to 12 (years 1 to 8). The closest schools for older students are Tapawera Area School and Murchison Area School. They are about 54 km and 59 km away by road.
What is Saint Arnaud's Climate Like?
Saint Arnaud has a temperate climate. This means it has mild temperatures. Even though it is about 650 metres high, it rarely gets much snow. This is because it is close to the Cook Strait, which brings warmer ocean air. Other towns at similar heights, like Lake Tekapo, often get more snow.
