Although a cadetship through Nelson Polytech was available it was not attracting Māori. Having now run for just over a year the scheme has changed this with 15 young Māori currently selected and training through the scheme. After completing their training, cadets will be encouraged and assisted to pursue employment either within their own iwi or DOC.

In keeping with with this settlement, the crown allocated 20% of all marine farming space created after 1992 to Māori. In this episode we visit Te Tau Ihu o Te Waka a Maui – the largest region of aquaculture practice in Aotearoa. Now on a larger commercial scale Māori continue a traditional practise of harvesting kaimoana with fostered partnerships across the community.

Local iwi help to protect and conserve the mouth of the Wairau river. The Wairau bar has for hundreds of years been the bread basket of local tribes, mainly Ngati Rangitane. The Wairau River is under threat, In 1997 there were 2655 acres of vineyards planted in Marlborough, today there is more than 22,000. The need to irrigate in a chronically dry area is just one of the threats to the river. Dairy farm runoff and increased use of agrichemicals has all contributed to the unavailability of clean water. Now Trust Power is aiming to build six new hydro power stations along the Wairau.

Ngā Whenua Rahui was set up in 1991 to negotiate with māori land owners for the protection of native forest and indigenous ecosystems on Māori land in a bid to preserve this precious taonga. It is not compulsory. The urgency is great as only one third of New Zealand’s forest cover still remains and every year it gets less. The remaining forests are home for many of our unique native birds. Many have been lost but in recent times there has been impressive gains in protecting and enhancing what is left with landownders working with organisations like Ngā Whenua Rahui.

A feature-length documentary that shows one of the great rivers of America in crisis while also telling the story of a "sidewalk Indian", Jack Kohler, who discovers his roots among the Klamath River tribes. For Kohler, the conflict is a journey of self-discovery as he uncovers the elemental bond between California native tribes, the river, and its most legendary denizen, the salmon. Kohler comes to the mouth of the Klamath River to make a film about the 1978 Salmon War. But an event occurs that brings the conflict into the 21st century. In May 2001, a federal judge's ruling under the Endangered Species Act (ESA) to cut off irrigation water sparks an angry protest from local farmers. Then in 2002, ignoring the ESA, the Bush Administration orders the unlimited release of water to farmers. Later that year, 80,000 spawning salmon die in the Klamath estuary, which leads to the collapse of the salmon fishery off the California and Oregon coasts. The polarization of Klamath Basin communities gives way to conflict resolution and consensus building. Recognizing that their livelihoods all depend on the health of the river, stakeholders who had been antagonists agree to share the water and to demand the removal of the four dams. The hopeful outcome of the conflict is a lesson in the interdependence of economic recovery with ecological restoration, and the value of finding common ground among competing interests.

In the 1960s Richard O'Barry enjoyed a lucrative career as a specialised animal trainer; he captured the five dolphins that were used in the popular television series 'Flipper'; and taught them the tricks and special commands they used on the show. Four decades later; O'Barry has renounced his former life as a trainer and become an animal rights activist; speaking out against the hunting of aquatic mammals and keeping them in captivity. O'Barry is not welcome in Taiji; a town along the Japanese coast where hunting dolphins is a major part of the local economy; but he and a group of activist filmmakers made their way into the city as well as the carefully guarded harbour in hopes of documenting the abuse of dolphins by fisherman and the poisoning of the waters that has taken a toll on the marine ecology. O'Barry and his colleagues captured some beautiful underwater footage as well as shocking images of how the town's fisherman have sullied the dolphins and their habitat; and director Louie Psihoyos has used this material as the basis for the documentary 'The Cove'; which received its world premiere at the 2009 Sundance Film Festival.

Only metres above sea level, the nation of Kiribati is on the front line of climate change. Maria Tiimon is determined to raise the world's awareness of its predicament. A personal story about a pacific nation on the frontline of climate change. The central Pacific nation of Kiribati is one of the countries in the world most vulnerable to climate change. Sea level rise and increasing salinity are threatening the lives of 105,000 people spread over 33 atolls in this remote corner of the Pacific. It's the same ocean, which for generations has sustained the country that is now the source of its destruction. The latest prognosis for climate change appears grim. Pledges made by industrialized countries at the Copenhagen and Cancun Climate Change Conferences to cut carbon emissions have fallen far short of their targets. Scientists currently predict temperature increases of between 3 and 6 degrees, and sea level rises of well over a metre, by the turn of the century. Only decisive global action will save Kiribati and its culture from disappearing.

Climate change is already affecting the world we live in but what are its implications for New Zealand and how can we slow it down?

Most of New Zealand's monitored waterways are polluted, but how has this happened? And is it possible to turn things around?

New Zealand's reliance on a clean green image is an environmental, social and economic issue, but how pure are we and what are we doing about it?

Molten lava bulging against the Earth's crust beneath America's Yellowstone Park will explode through with devastating effect - it's just a question of when, say scientists.

An investigation of the harmful pollutants to which New Zealanders are exposed. Our Dirty Little Secret focuses on the Angland family – an average young kiwi family – two parents and three children. We follow them over the course of a single day – at work, at school, on the road, at home and at play. Along the way, we discover that the environment they live and move in may be green, but there’s no way it’s clean. http://www.topshelfproductions.co.nz/Shows/our-dirty-little-secret/

Changing The Future The Lord Of The Rings revealed the wilderness of New Zealand to movie watchers worldwide. But while the country’s wild places are popular with both locals and a growing number of visitors, most people actually live in cities. And it is in their cities that most New Zealanders put their environment at risk.

Farming is just as vital to New Zealand’s wealth as it is to the fictional Shire. With its clean, green Middle-earth image, New Zealand cannot afford to ignore the reality of how farming affects its environment.

Like the woods of Middle-earth, the forests of New Zealand are not immune from destructive forces. The trees are under attack from a predator just as voracious as Saruman’s orcs. Is it really as Treebeard laments – does nobody care for the woods anymore?
