Sea lions and fur seals are the protected species most directly affected by fisheries in New Zealand waters, along with seabirds and dolphins. Trawling poses a risk to both species. Fur seals can also be captured by other fishing gear, including long lines. Estimating the bycatch of sea lions and fur seals indicates the pressures they face from current fishing practices.
The New Zealand fur seal Arctocephalus forsteri is classified as not threatened with extinction and its population appears to be increasing and extending back into its historical range (where they were commonly found) (Baker et al, 2010). They have a wide distribution, but are more common in the southern parts of New Zealand.
The Fisheries Act 1996 designates the New Zealand fur seal as protected and requires mitigation measures to reduce bycatch (Ministry for Primary Industries, 2014).

The unintended catch of marine species other than the target species puts pressure on the populations of marine species by removing individuals or potentially modifying ecosystems.

Along with sea lions, fur seals, and dolphins, seabirds are the protected species most directly affected by fisheries in New Zealand waters (exclusive economic zone and territorial sea). Estimating seabird deaths from bycatch in commercial fishing is one way of assessing the pressure some seabird species face from current fishing practices. About one-third of our 92 resident seabird species and subspecies are considered to be threatened with extinction. We report on the risk of death from commercial fishing for 70 seabird species and subspecies.
This data has been significantly revised since that reported in Environment Aotearoa 2015, with the estimated total bycatch of seabirds increasing by nearly 1400 birds (30 %) on average across the comparable years 2002/3 – 2012/13. This revision is due to an updated and more unified modelling approach being applied by the data providers.

The estimated annual seabird bycatch in trawl and longline fisheries is reported for Salvin’s albatross to illustrate effects on a threatened bird species with a very high risk of fishing-related death.
This data has been significantly revised since that reported in Environment Aotearoa 2015, with the estimated total bycatch of seabirds increasing by nearly 1400 birds (30 %) on average across the comparable years 2002/3 – 2012/13.

New Zealand’s four million km2 marine environment is diverse, with a range of coastal habitats and offshore seabed environments. There are also many marine species unique to New Zealand. Marine protected areas conserve or manage some of these unique habitats and species, while a range of other tools also provide marine protection. We report on the area covered by these tools as an indirect measure to understand the state of the marine environment.
Marine mammal sanctuaries are one of the marine protection tools used. They are designed to protect New Zealand’s unique range of marine mammals by reducing harmful human impacts, particularly in vulnerable areas such as migratory routes and breeding grounds. Each marine mammal sanctuary has a specific set of restrictions based on the species that occupy, or pass through that particular area.

Seabed trawling is the practice of towing fishing nets near or along the ocean floor. The towing process can physically damage seabed (benthic) habitats and species. It can also stir up sediment from the seabed. This creates sediment plumes that change light conditions. This can affect marine species (for example by limiting their capacity to generate energy through photosynthesis) and smother sensitive species.
This dataset relates to the "Commercial seabed trawling and dredging" measure on the Environmental Indicators, Te taiao Aotearoa website.

Seabed trawling, when fishing nets are towed near and along the ocean floor, can physically damage seabed (benthic) habitats and species. It can also stir up sediment from the seabed, shading or smothering marine species. For this measure, coastal areas are waters shallower than 250m.
