Down To Earth has been giving New Zealanders a greener household cleaning option since 1989. We were first to launch a safer, sustainable alternative to the harsh chemical cleaners around at that time, and today our range continues to lead the way in delivering brilliant results at an affordable price, while caring for you and the environment.
* No Phosphates. Contains no added phosphorus. Levels below 0.5% may be present. Phosphate free products are less damaging in river systems because phosphate promotes algal growth which can clog up rivers.
**Down to Earth helps to minimise waste in the environment as the surfactants are readily biodegradable and fully conform to Australian Standard AS4351.
*** Recycled & Recyclable packets. Down to Earth packets are made from 95% recycled fibre, and are 100% recyclable. Down to Earth laundry and tablets packets, and the laundry and dish wash bottles are 100% recyclable(as are the caps, where facilities exist). The scoop in our laundry powder is also 100% recyclable.
The North Island sub-species of Hector’s, the Maui’s dolphin, numbers just 111. They are critically endangered. The situation is compounded because their population may include fewer than 60 mature animals, with only an estimated 25 breeding females.
They are found only off the north-west coast of the North Island. Like its cousin in the South Island, they are so small they could fit into a bathtub. They are truly unique.
As well as being slow breeders the pool of potential mates for Maui’s dolphins is very small, meaning that inbreeding may occur. Inbreeding reduces the gene pool and creates a higher chance of birth defects and genetic problems.
In the 19th Century Maui's dolphins were found around the North Island coastline, from Tauroa Point in Northland , south around Wellington and back up to mid-Bay of Plenty. Maui’s dolphins are now only found from Maunganui Bluff (near Dargaville) to just south of New Plymouth - most commonly between Manukau Harbour and Port Waikato.
In the 1970s most strandings of Maui’s dolphins were around the lower North Taranaki Bight.

At Down to Earth, we’re not only passionate about safeguarding the planet we’re also concerned about protecting the precious species on it.
As such we are proud to be Forest & Bird’s Official Guardian of the critically endangered Maui’s and endangered Hector’s dolphins. With our ongoing support, Forest & Bird can further their conservation efforts by safeguarding the current population of these rare and special animals*, educating schoolchildren, the public and fishermen, and lobbying Government for ongoing protection programmes.
*At this moment in time the Maui’s dolphin is in a critical position as their population is estimated at just 111 individuals and may include fewer than 60 mature animals, with only an estimated 25 breeding females. The Hector’s dolphin is also under extreme threat, with the population having declined to just above 7000 individuals (down from an estimated 27,000 just 35 years ago).
Maui’s and Hector’s dolphins are unique to New Zealand. They are only found off the coast of New Zealand. They are our very own dolphins. Both the South Island Hector’s dolphin and the Maui’s dolphin are listed internationally as species threatened with extinction.
Yes and No...The North Island Hector’s dolphins - Maui’s dolphins - were once called Hector’s dolphins. However Maui’s became separated from their South Island cousins (and stayed apart) so that now the North Island Hector’s are genetically distinct from the South Island Hector’s.
The female Maui’s and Hector’s dolphins only produce one calf every 2 to 4 years and do not start breeding until they are 7 to 9 years old. This slow rate of reproduction makes Hector's dolphin populations vulnerable to deaths caused by human activities such as fishing.

Not only are Hector’s rare, they are also very small (less than 1.6m long), which makes them the world’s smallest dolphin. Once found around most of our coastline, there were an estimated 21,000 to 30,000 in the 1970s, but now there are less than 8,000 Hector’s dolphins alive.
They are listed as endangered by the IUCN (International Union for the Conservation of Nature), meaning that the Hector’s dolphin is at serious risk of extinction.
The biggest danger to Hector’s and Maui’s dolphins is set netting. Set nets are responsible for more than 60% of all deaths where the cause of death is known. However, set nets are likely to pose a much higher risk because many deaths aren’t reported.
Hector’s prefer shallow water (usually less than 100m deep). They feed on fish that swim close to the surface in shallow, often sandy-bottomed waters, making frequent short dives to find food, such as flounder, red cod, mackerel, crabs and squid.
The Hector’s are homebodies — they usually stay within the same areas. As a result Hector’s populations are highly fragmented, with limited mixing between populations.
They use echo-location to locate their prey — it’s like seeing with sound, a kind of marine radar. Dolphins send out a stream of high frequency clicking noises and when the sound strikes an object it bounces back and the dolphin can tell by listening what the object is - what kind of fish it is, how far away it is and how fast it is moving. In familiar areas, their echo-location is turned off, which means they may not detect dangers like set nets.
Of all the dolphins seen in New Zealand waters, Hector’s (and Maui’s) dolphins are the only ones with a rounded dorsal fin —all other species of dolphin found in New Zealand waters have crescent shaped fins that are more pointed. They also have distinctive black markings on their fins, tails, flippers and faces.
The Hector’s dolphin was named after Sir James Hector (1834 to 1907), who was the curator of the Colonial Museum, in Wellington. He examined the first specimen found of the dolphin and was the most influential New Zealand scientist of his time.

There are a number of threats to Hector’s dolphins, including boat strikes, trawling and pollution, but the main threat is set netting. Dolphins are accidentally caught in the set nets and drown. The Maui’s and Hector’s dolphin populations can’t afford any more deaths from fishing.

Set nets (used in commercial, recreational and customary fishing) are responsible for more than 60 per cent of all known deaths (where the cause of death is known).
These nets are used to catch fish in coastal waters, which is where Maui’s and Hector's dolphins live.
Set nets are indiscriminate: as well as dolphins they kill a wide range of other marine mammals and seabirds, and other species of fish that fishers do not intend to catch.
A study by NIWA, the Ministry of Fisheries and fishing industry representatives (March 2008) shows that 110-150 (estimated) Hector’s dolphins are killed in commercial set nets every year.
Trawling also catches fish indiscriminately - many are unwanted species that are not targeted by fishers (including dolphins and fur seals).
Although trawling is a less significant threat to the Maui’s and Hector’s than set netting, trawling does impact these dolphin populations. For example in April, 2006, three Hector’s dolphins were caught by one single commercial trawl vessel around the Marlborough Sounds.
A much lesser threat but nonetheless a killer is boat strike – where dolphins are sliced by the propeller of careless boats. Marine Mammal protection rules require boats to slow down or dolphins. But accidents still happen.
In May 2008 the Government announced new measures to protect Maui’s and Hector’s dolphins that recognised the impact of set netting and addressed a number of other threats. The protection is not as comprehensive as Forest & Bird would have liked however the new measures are still a significant step towards halting further population declines.
Forest & Bird is particularly concerned that the new measures do not protect Maui’s and Hector’s throughout their range - there are still a number of areas where Maui’s and Hector's dolphins are unprotected.
South Island Hector’s dolphins have no protection around the top of the South Island. There is also very little protection off the West Coast of the South Island, where 70% of the population lives. Recent Hector’s deaths at Kaikoura and Timaru also highlight the need for greater protection in these areas too.
For Maui’s dolphins the set netting ban does not extend offshore enough or south enough into areas where Maui’s dolphins have been recently sighted. (Stuff.co.nz video of sighting off Taranaki)
