Our fish stocks are affected by commercial, customary, and recreational fishing, and environmental pressures (eg ocean temperature, acidity, and productivity). The Ministry for Primary Industries uses three performance measures to assess influences on fish stocks: a soft limit (below which a rebuilding plan is required), a hard limit (below which closing a fishery should be considered), and an overfishing threshold (where the rate of extraction is higher than the rate of replenishment).
This dataset relates to the "State of fish stocks" measure on the Environmental Indicators, Te taiao Aotearoa website.

This indicator measures the concentrations of four heavy metals (lead, copper, zinc and cadmium) against the Australian & New Zealand Environment and Conservation Council (ANZECC) guideline values for toxic substances in estuarine sediment.

Heavy metals occur naturally in estuaries, but high concentrations suggest contamination from another source. The metals can be transported along waterways from urban environments (and, for cadmium, from farmland) and accumulate in estuarine and coastal sediments. Heavy metals are toxic although some such as copper and zinc are classed as micro-nutrients at very low concentrations. They accumulate in sediment, where they can be taken up by organisms, and are harmful to species and habitats. They also bio-accumulate (are found in higher concentrations in species further up the food chain).

This indicator measures the rise in annual mean coastal sea level relative to land. The national mean is derived from four long-term monitoring locations across New Zealand: Auckland, Wellington, Dunedin and Lyttelton. We also report the trends over time, from the beginning of our records until 2018. Relative sea-level rise includes the vertical land movement of the surrounding area (for example, a sinking landmass increases the rise in ocean sea level).

We report the change in annual mean coastal sea level to 2018 against the established baseline (mean sea level for 1986–2005) for the long-term sites plus an additional two sites: Moturiki (Mount Maunganui) and New Plymouth. These are not included in the national mean due to shorter records. We also measure the national annual sea-level rise for two time periods: the start of the records to 1960, and 1961–2018.

Data are for 15 measures of coastal water  quality at monitored sites in New Zealand. These 15 measures are dissolved oxygen, pH, salinity, temperature, visual clarity, turbidity, suspended solids, ammoniacal nitrogen, nitrate-nitrite nitrogen, total nitrogen, dissolved reactive phosphorus, total phosphorus, faecal coliforms, enterococci, and chlorophyll-a.

These data estimate the occurence of extreme wave events in coastal and oceanic waters for 2012, particularly for wave events where significant wave height exceeds a threshold of 8 metres and for a period of at least 12 hours. Significant wave height is defined as four times the square root of the variance of sea surface elevation due to wave motion.

These data provide a snap shot of beach litter surveys submitted by Citizen Scientist ‘Monitoring Groups’ up to April, 2019. As defined by the United Nations Environment Programme (UNEP, 2009), marine litter is any persistent, manufactured or processed solid material discarded, disposed of, abandoned or lost in the marine and coastal environment. Marine litter washed onto beaches is one of the most obvious signs of marine pollution, and can have either land or sea-based origins. Land-based sources of marine litter include input from rivers, sewage and storm water outflows, tourism and recreation, illegal dumping, and waste disposal sites. Sea-based sources include commercial shipping, fisheries and aquaculture activities, recreational boating and offshore installations.

The South Island Hector’s and Māui dolphins are among the world’s smallest marine dolphins. Both are subspecies of the Hector’s dolphin Cephalorhynchus hectori. These coastal dolphins are endemic to New Zealand, which means that they are not found anywhere else. The Māui dolphin is found in the inshore waters of the west coast of the North Island, most often from Maunganui Bluff, north of Dargaville, to New Plymouth. The South Island Hector’s dolphin (hereafter referred to as ‘Hector’s dolphin’) is mostly found in the inshore waters around the South Island. Both subspecies are threatened with extinction: Hector’s dolphins have a population estimated at 15,000 and are classified as nationally vulnerable, while Māui dolphins have a population estimated at 63 individuals over one year old and are classified as nationally critical (Baker et al, 2019; MacKenzie & Clement, 2016; Baker et al, 2016).

Dolphins can become entangled in fishing gear used by both commercial and recreational fishers, with set nets posing a particularly high risk. The accidental capture of marine life in fishing gear is typically referred to as bycatch. Reporting the causes of death of protected species and specifically identifying the number of animals killed as a result of fishing activities helps us understand the pressures our protected marine species face from fishing.

DOC’s Hector’s and Māui dolphin incident database 1921-2018 provides data on reported deaths of Hector’s and Māui dolphins.

This indicator measures the number of reported Hector’s and Māui dolphin deaths from entanglement, categorised by type of fishing gear where possible, since 1998. The number of entanglements is compared to the total number of reported deaths.
