Manihiki – the island of black pearls

The Cook Islands’ main source of income is tourism but at the moment our borders are closed and there have been no overseas tourists since March 2020.
Tourism Cook Islands, Air Rarotonga and Island Hopper Vacations got together to organise excursions to the Pa Enua (outer islands) for locals at fantastically discounted prices.
The aim was to prepare new products for when our borders are open again.
There were two excursions, one to the northern group (Pukapuka, Manihiki and Penrhyn), the other to the southern group (Atiu, Mangaia, Mitiaro and Mauke).
We were lucky enough to get on to the first northern group tour.
Here is information about our second stop – Manihiki.

The flight from Pukapuka to Manihiki takes about an hour in the Citation jet.
Manihiki was once known as Humphrey Island and is also called, informally, the island of black pearls.
When we landed it was raining and the airport was crowded – relatively speaking.
The jet had been chartered to carry a group to Rarotonga so while we were greeted with colourful ei and delicious nu, the plane was refuelled (not easy in wet and windy weather).

The coral atoll of Manihiki has over forty motu (islets) surrounding a deep lagoon about nine kilometres wide. The two main motu are Tukao, where the airport is situated, and Tauhunu where we stayed for two nights.
To get from the airport to Tauhunu we climbed aboard an aluminium dinghy – the main method of transport in the northern atolls.
Some of the group stopped at the two over-water bungalows of Manihiki Lagoon Villas. Phil and I carried on to Numahanga Homestead, further into Tauhunu village.

Numahanga Homestead

The homestead was built by Tekake William, the father of black pearl farming in Manihiki. It’s certainly built to house a lot of people. There’s a huge kitchen/dining/living/sleeping room. As well as a double bed, two large sofas could also be used for sleeping and on the wide covered verandas that surround the house are several more beds.
The bathroom and shower are accessible from the veranda as are several other rooms that were not in use while we were there.

Fabulous food

Breakfast at Numahanga Homestead in Tauhunu village - eggs, bacon, toast, pancakes pawpaw with lime juice, toast.

The fridge was well stocked but we never needed to cook because our host Gabriel (a relative of the late Tekake) and his wife Joyana brought along our meals – breakfasts and dinners.
And what meals they were.
BBQ tuna and other fish, sashimi, salads, rice, taro, coconut crab, uto pancakes with fresh nu to drink.
For breakfast we were treated to pawpaw with lime juice, eggs, sometimes fried, sometimes scrambled, bacon, pancakes with maple syrup, and toast.
Far too much for just the two of us so I hope the leftovers were recycled!

En route to a pearl kaoa

One of the highlights of our time on Manihiki was a visit to a kaoa – a pearl farm centred on a coral outcrop in the lagoon.
We walked to the wharf on the lagoon side of Tauhunu checking out the black tip reef sharks swimming around the fish gutting station (the sharks do a great job of keeping the area clean) before collecting the rest of our group plus food, fishing gear and pearl farming tools.

The Cook Islands pearl industry developed quickly in the 1980s and caused a ‘gold rush’ mentality. Prices and global demand were high and the buyers coming into the Cooks were buying everything the Manihiki farmers produced.
In its heyday in 2000 black pearls worth $18m annually were produced by some 200 farmers.
But as more and more oysters were crammed into a small lagoon with limited food and oxygen, a bacterial disease broke out and devastated the industry.
Many farmers gave up altogether, entire farms were abandoned and the number of oysters in the lagoon plummeted, back to a level which nature could support.
From about 2006 the Manihiki Island Council and Ministry of Marine Resources have overseen sustainable pearl farming practices for the lagoon.
There are now around 25 pearl farmers who sell most of their pearls locally although since our borders closed because of covid-19 there are no tourists to buy them.
In the late 1990s the population was about 600 but following cyclone Martin in 1997 and the collapse of the pearl industry it has dropped to about 200.

A day on a kaoa

This farm was once the home of Tekake William. The house and outbuildings are substantial although they have fallen into disrepair. Pearl farmers no longer live on the kaoa but just visit them when there is work to be done.

The oysters

Seeded oysters are attached to strings called chaplets that are suspended in Manihiki lagoon. It takes about two years for a pearl to form inside the oyster.

A boatload of boys came to the kaoa with us, some to fish for our lunch, some to cook it and some to demonstrate pearl farming.
Oysters are attached to strings, called chaplets, dangling in the lagoon. Once an oyster has been seeded it takes about two years for a pearl to develop.
The boys dived to collect a basket of oyster shells and then hacked off the marine growth on the shells, a messy job.

When checking to see if a pearl has formed, first the marine growth must be cleared from the outside of the shell.

This rubbish can’t be dumped back into the lagoon, it has to be taken to land on one of the many uninhabited motu. The huge mounds soon become fly-infested but once the flies have finished the mounds are clean and dry.
The farmers have a range of special tools for checking pearls or re-seeding the oysters.

First the shells are prised slightly apart and a technician peers inside to see if there’s a pearl nestling in a sac. If so there follows a delicate probing and cutting to release the pearl. If not, the oyster will be eaten!
Our group had the chance to probe and they found several keshis (mal-formed pearls) and a couple of beauties.
An oyster that produces a good pearl is re-seeded and put back in the lagoon on a new chaplet. The ’seed’ actually irritates the oyster and it secretes nacre to surround and seal it off thus forming the pearl.

Time for lunch.
This kaoa’s umu is a wishing-well-shaped structure with a pit for stones to be heated with driftwood and old, dead trees. BTW the stones are imported from Rarotonga because the local coral boulders just split when heated.
Tuna slices, clams, crayfish, coconut crab and other fish didn’t take long to cook on the BBQ plate. The crew also ferried over rice, bananas, taro and a special Manihikian version of poke. Cold pawpaw juice to wash it all down.

Looking for crabs

Blue and brown coconut crabs can live up to 50 years.

After lunch there was time for swimming or snorkelling then we headed back to the mainland stopping off at an uninhabited motu to hunt for coconut crabs – but NOT to catch and cook them, just to look at them in their natural environment.
Most Manihikians keep pigs but as the population dropped when families left the island people didn’t take the pigs with them and there are now a lot of wild pigs around. They can travel between some islets at low tide but foraging pigs damage the crabs’ habitat so motu with pigs have very few coconut crabs.
However this was a pig-free motu.
Nature walk
We enjoyed a very pleasant nature walk although jandals aren’t the best footwear for scrambling over fallen palm trees, kikau fronds, coconuts and scrubby bushes.
A fully grown coconut crab is a very impressive creature. The ones we saw were brown and blue. They can climb coconut palms but usually live in holes at the base of the trees, although one we were shown lives in a shallow cave in a rock wall.
They can live to about 50 years – much older than the boys who found them for us. The locals know where to find them but only catch them when needed. Got to say, I preferred looking at them to eating them.
We left them to return to their holes and sailed back to Tauhunu.

Tukao

A memorial in Tukao village on Manihiki list the names of 19 victims of cyclone Martin in November 1997.

Tukao village is smaller than Tauhunu but still has a school and a government administration centre.
Outside the centre is a memorial to the nineteen people lost when cyclone Martin struck on 1 November 1997. Ten bodies were never recovered.
After Martin the New Zealand government built several cyclone shelters but they are now mostly dilapidated. They clearly haven’t been used for many years, not really surprising since the population has decreased so much.

New Zealand built cyclone shelters on Manihiki after cyclone Martin but most are now derelict.

We walked from the village to the airport along a path by the side of the runway.
Fortunately the Citation had returned from its charter to Rarotonga so we said farewell and thank-you to the people who’d looked after us and were soon on our way to Penrhyn, the final atoll on our discovery tour.

Check out Pukapuka, the first stop on our journey.
