In 2012 over 3600 people were surveyed as part of a formal research programme. A small number of native species, including the kiwi, were tagged as being "quintessentially kiwi".
Overall there is a clear acknowledgement of the need for environment support.
Approximately 70,000 kiwi are left in New Zealand - 200 years ago there were millions. By the turn of the 21st century, there were fewer than 100,000.
Nine out of ten kiwi chicks born in the wild die before they are six months old. Most are killed by predators. The introduction of stoats, ferrets, rats, cats and dogs have seen the demise of many native species.
About half of all kiwi eggs fail to hatch because the adult bird is disturbed by predators.
The Okarito Rowi and Haast Tokoeka were facing a bleak future with populations as low as 250, before receiving a helping hand with the BNZ Operation Nest Egg programme in 2005.
Little Spotted Kiwi have been extinct on the mainland for decades, but about 1500 survive in protected sanctuaries.
The Great Spotted Kiwi, which once were numerous throughout the South Island, are declining at a rate of 2% p.a.
In 2005 the New Zealand Conservation Trust, in partnership with Willowbank Wildlife Reserve and the Department of Conservation, became involved in the BNZ Operation Nest Egg programme. The initial focus was on the two most endangered of all kiwi species, the Rowi and the Tokoeka. In 2007 the Trust became involved in a breeding programme for the Great Spotted Kiwi.
