Tory Channel Entrance

Tory Channel also known as Kura Te Au separates Arapaoa Island from Te Waipounamu.

Tidal streams of up to seven knots flow through the entrance to and from Cook Strait. These tidal streams cause a great deal of turbulence, which can be very dangerous.

In N sector winds the Tory Channel entrance usually poses little problem. However, S sector winds generally create a heavy ground swell and this swell, meeting the shore line, piles up creating a steep sea.

If combined with a strong outgoing tide, a series of dangerous breaking seas occur just outside the entrance. Passage through the entrance is undesirable in such conditions, especially in undecked boats, as they can be easily swamped.

Low-powered vessels trying to enter from Cook Strait against the outgoing tides will find least current close to West Head as far as Taranaki Rock. From there, the boat should be headed for Okukari Bay and allow itself to be swept over close to the northern shore. A counter-current forms along this area, as far around as Whekenui Bay.
If leaving Tory Channel against an incoming tide, least current is usually experienced close to West Head. During the incoming tide the current tends to sweep across the outer part of the entrance to the east and can carry boats on the dangers out from East Head.

There are several dangerous rocks in this area. Taranaki Rock on the West Head side dries at Spring Low Water and should be given a wide berth as the strong tide can easily sweep a boat on to the rock. There are rocks out to sea from both East and West Heads and both of these points should be given a clearance of 100 metres. From East Head to westward into the channel, there are rocks below the surface up to 30m from the shore.

At night the Tory Channel entrance is marked by a sectored light on East and West Heads. There are two leading lights in Okukari Bay which, when in line, indicate the centre of the channel.

The interisland ferries give warning of their approach to the entrance by a general call on VHF channels 16 and 18. These ships must be given right of way, as once in the entrance any emergency manoeuvres to avoid small craft would be nearly impossible. If in the entrance at the time that the ferry passes, keep well to the side and there will be plenty of room.

The channel and many other landmarks in the area are named after the Māori oral traditions of Kupe, a semi-legendary seafarer from Hawaiki, the traditional Māori place of origin, who explored New Zealand sometime in the thirteenth century.

While exploring New Zealand, Kupe discovered the channel. In it he met the giant octopus Te Wheke-a-Muturangi, a creature he had fought previously during his voyage. A fierce battle ensued, with Kupe and his crew hacking at Whekenui’s tentacles with weapons.

The giant octopus was finally killed with a massive downwards blow to the head, known as an arapaoa. The death of Whekenui has been commemorated in the naming of several local landmarks, including Whekenui Bay, the location of the creature’s death, and Arapaoa Island, the island separated from the South Island by the channel itself.

The channel is also named for the legend, its Māori name, Kura Te Au, means the channel red with blood. While oral tradition attributes the red hue of the water to the blood of the slain octopus, scientists have determined that the red tone of the water in the channel is due to the high density of krill and plankton in the area.1

Captain Cook was the first European to explore Kura Te Au in 1774, when he sailed out as far as the entrance. After Cook's visits, few European ships entered the Sounds until the arrival of the whalers and in 1839, the New Zealand Company ship, the Tory. The Tory spent a significant amount of time in Kura Te Au visiting bays such as Te Awaiti to gather information about land ownership.

It was following this visit that the Europeans named Kura Te Au, Tory Channel.2

From the late 1820s until the 1964, the entrance to Tory Channel/Kura Te Au was closely associated with the whaling industry. John ‘Jacky’ Guard is believed to have established the first whaling station at Te Awaiti Bay in 1827 and a number of other early whalers and traders, including John ‘Jacky’ Love, Richard ‘Dicky’ Barrett and Joseph Thoms were residents in the area.

While the whaling infrastructure and huts were located in the bays, a lookout was maintained on West Head, one of the headlands at the channel entrance. When whales were sighted from the lookout an alarm was given and the whalers would set out into the Cook Strait/Te Moana-o-Raukawa in their whaleboats.3

While whaling declined from the 1840s, it was revived again in the twentieth century by the Perano family. In the early years of their operations, the whale-chasing boats were moored at the mouth of Tory Channel/Kura Te Au near Taranaki Rock outside a small bay called, Boat’arbour.4

As the whaling operations grew, the station was moved to Fishermans Bay. At this time, the Perano family also started to use a lookout based upon West Head, or as it was to become known, Lookout Hill. The lookout was located about 55 metres above sea-level about 100 metres west of the West Head shipping beacon.5

Lookout Hill was where the Peranos and employees sat to watch for whales in the strait between May-August. Exposed to the weather, men would sit for hours at a time looking through binoculars.

Initially there was no shelter but eventually a hut was built to provide some protection from the wind. In addition a wooden floor, wood stove and a large glass viewing window were added.6

Evidence of the lookout hut remains.7
