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.

Even though we’re still in the last month of Winter, it’s starting to feel more and more like Spring! It was a cracker weekend here in Kaikōura with amazing sea conditions and picture perfect days to go along with it.

This week we saw semi-residential whales Tiaki, Matimati, Tutu and Aoraki as well as some visiting Sperm Whales to our region. It’s so encouraging to see these whales returning to our region time and time again as they are always our favourites to see out on the water.

Four Humpback Whales were seen on our tours this week. September marks the end of their annual migration, so it’s not too long until we stop seeing the most acrobatic whales on the planet on our tours completely until next year’s journey takes them back through Kaikōura waters again.

Wednesday’s tour got to see a pod of 300 Dusky Dolphins playing with a Giant Warty Squid, also known as the Longarm Octopus Squid. These squid grow up to two meters in length and are a staple part of the Sperm Whale’s diet. A truly spectacular sight to see!

We currently have an end of winter sale on at our Retail Store at the moment, a whopping 25% off all hoodies, jackets and merino items! We need to make room for new summer stock, so head over to our online store to get your hands on some winter goodies.

REGULAR, SCHEDULED CLOSURES OF STATE HIGHWAY 1 SOUTH OF KAIKOURA

There is a possibility of short delays and it will be 30km/hour through parts of the route. Inland Route 70 remains open 24 hours a day 7 days a week.

As we enter into the cooler winter months it is a good reminder to take extra care on the roads and to check the NZTA website for road updates before traveling.

Progress is continuing to be made on the repair of the Kaikōura Marina, with the modified trailer and public jetty now being used for launching our vessel Tohora. This is due to tidal restrictions and repair work as a result of the coastline lifting by +1.0m. All our berths have now been removed. This is an end of an era but we are excited to see our new and improved marina once it is completed! The use of the modified trailer and public jetty will continue until further notice. It is anticipated that the Kaikōura Marina will be fully restored in October 2017. Below is a graphic (indicative only) of what is being restored at the marina.

Currently our available tour times are based around the tide times on the day and may differ from the tour times originally advertised, please bear with us as we continue to work toward being fully operational again. For an update on the tour times available, please contact our Customer Service team directly either by email on res@whalewatch.co.nz, phone +64 3 319 6767 or free phone 0800 655 121 (within NZ) and they will be able to help you with your inquiry.  Please note we are operating at a reduced capacity in the interim with up to 3 tours available per day. Please contact our team prior to arriving in Kaikōura to secure a space on one of our tours and to save disappointment.
