Canyon & Sub-tropical Environment

The waters off the Kaikōura Coast provide a unique habitat for sea-life. Comparisons have been made between the waters of the Kaikōura Coast and the Africa’s Serengeti Plain, such is the abundance of life found in the waters off the coast. But how is it that this part of New Zealand’s South Island coastline was such a great concentration of oceanic life?

The big deep

The Kaikōura Canyon is a submarine canyon located around 800 metres off the Kaikōura Coast.  It stretches for over 60 kilometres and reaches depths of up to 1200+ metres.  The canyon is part of the Kermadec Trench system which extends far out into the Pacific Ocean.  The trench has been formed as one of the Earth’s tectonic plates, the Hikurangi Plateau, slides beneath the Indo-Australian Plate.

A cold-water supermarket

As cold water moves along the base of the trench towards the coast, it begins to rise, bringing with it nutrients from the deep ocean.  The nutrients encourage a food chain which begins with tiny plankton and goes all the way up to the whales and dolphins you can see from your Whale Watch boat.  Deep water fish also follow the cold water currents, making Kaikōura such a spectacular place to go fishing.

On the waterline

Encouraged by the oceanic bounty of the trench, many species of mammal, birds and crustaceans flourish along the shallower fringes of the coast.  The fat New Zealand fur seals you can see basking on the rocks find all the food they need in amongst the kelpy reefs and deep fissures of the seabed.  And, of course, the creature which gave the region its name, the crayfish (kai = food; kōura =crayfish) flourish in the nutrient-rich waters.  The cliffs and crags of the coast and the Kaikōura Peninsula offer roosting-places for the myriad species of sea-birds which harvest the waters off the Kaikōura Coast; ocean-going seabirds congregate off-shore where schools of fish provide easy pickings

The skyline

Rearing almost straight out of the ocean, the Seaward Kaikōura Range and the Inland Kaikōura Range have been formed by the same immense pressures which have formed the Kaikōura Canyon.  As the Hikurangi Plateau pushes under the Indo-Australian Plate, it rumples the edge of the plate up just like a carpet being pushed up against a wall.  The resulting mountain ranges are spectacularly rugged and unstable, as the forces of erosion seek to tear them down as fast as the tectonic forces push them up.  The steep creeks and rivers which flow down from the ranges carry nutrients and minerals which further enrich the waters of the great oceanic supermarket off the Kaikōura Coast.

We had some stunning weather over the weekend along with some great sightings on our tours. Not only were we able to see sperm whales but also the rare opportunity of seeing a pod of beaked whales pass by the Kaikōura coastline. Not a common sight at all and one that is very treasured by all when we do.

Over the weekend we also had a visit from a couple of the crew from Emirates Team New Zealand with the America’s Cup. It was great to have the opportunity to see the cup up close. Check out this video to see how the afternoon went.

The Huttons Shearwater (Tītī) are special to us in Kaikōura. Their habitat sustained considerable loss during the Nov 2016 earthquake. Please take the time to vote for them as Bird of the Year and this status will help secure the much needed funding for more research so we can plan for their future.

Something worth celebrating...

Restoration work on the Kaikoura marina begun 10 months ago, and over the weekend we celebrated being able to now use berth 3 & 4. We have been using our trailer unit & the public jetty for some time now so to be able to pull up into our berths is quite an exciting feat. We still have a wee way to go but this is a HUGE step closer to being fully operational. We are very thankful for the amazing work the harbour repair crew are doing in what are at times trying conditions. We are excited to see our new and improved marina once it is completed! We cannot thank the tireless effort that the workers have put in to get us to this stage especially in what has been trying conditions at times.

More great news…

We thank you all for your patience over the last 11 months with the changing tour times with having work in line with the tides but with being able to now use berth 3 & 4 it means that we are now back running on our original fixed tour timetable. 0715, 1000, 1245 & 1530 (Nov-Mar)
