New Zealand is renowned for its natural environment – beautiful beaches, movie-set mountains and pristine national parks. But though it makes for a good postcard, it doesn’t show the full picture of how we interact with our environment or the risk we run of ruining it for future generations. 

As part of our theme of Impact, The Wireless looks at seven environmental threats the country faces: overfishing, waste, water degradation, fracking, air pollution, pests and erosion. 


The fishing industry contributes an average of over $1.3 billion in export earnings to the New Zealand economy each year and 424,693 tonnes of fish were caught commercially in 2009. Commercial fishing and trawling are thought to have the greatest overall impact on New Zealand’s marine resources and, if unmonitored, have the potential to impact habitats and deplete fish populations.

Tasman Bay in Nelson suffered from major over-fishing in the late 1970s when vast numbers of spawning snapper were taken by pair trawlers in the bay. The region has implemented tight restrictions to prevent this occurring again. 


In New Zealand, land filling is the most common method of solid waste disposal with the most recent annual figure of 3.2 million tonnes of waste being sent to municipal landfills. Programmes to minimise the impact of waste disposal in New Zealand’s focusses on the ‘5Rs’ of reduce, reuse, recycle, recover, and manage residual waste.

Water degradation  

The degradation of rivers and lakes has potential risks for New Zealand’s ecosystems, for the economy, for food gathering and for the country’s international reputation. There have been strong increasing trends in phosphorus and nitrogen, particularly in catchments predominantly in farm land. 

WATCH: We asked your opinions on the quality of water in New Zealand’s rivers. 

Approximately $500 million of government and community money is currently committed to the clean-up of lakes, rivers and streams in New Zealand. 


Fracking, or hydraulic fracturing, involves the injecting of chemicals into the earth at high pressure to extract previously inaccessible oil and gas. The practice is controversial, with polarised views about its impact on the natural environment.

In New Zealand, the practice is mostly used in Taranaki and the amount of gas and oil extracted using the method is rising. Exploration has occurred in the Waikato region and could spread to other parts of the country if oil is discovered in significant quantities, though the Christchurch City Council voted unanimously to declare it a fracking-free zone.   

Air pollution

In New Zealand cities, air contaminants are attributed to a high dependence on private vehicle usage and inefficient heating. Higher levels of CO2 in the atmosphere contribute to greater health problems, including respiratory problems, asthma attacks and reduced immunity.  


Stoats and rats pose a growing threat to New Zealand’s native bird population. This year, between $9 million and $12 million will be spent on the largest ever pest control programme covering 700,000 hectares.

The nesting Westland petrel are at high risk of predation and only around 4,000 birds exist in the Punakaiki area of the South Island’s West Coast. Te Papa researcher Susan Waugh is studying the birds and how the deomgraphics are changing over time. 



The Ministry for the Environment says accelerated erosion is “the most serious and the least reversible of soil degradation problems”. Many forms of erosion exist in New Zealand including mass movement due to heavy rain and storms, surface caused by wind detaching soil particles from the surface and streambank that occurs when banks have been cleared of tree cover.
