The report comprises four Parts. Part 1 presents an overview of risk analysis and its general application to the management of New Zealand's indigenous fauna and sets out a framework for risk analysis for indigenous fauna with reference to the example analysis for indigenous parrots in Part 3 of the report. Part 2 lists the indigenous vertebrate fauna populations of interest and considers, in general terms, the range of disease agents that need to be covered. A semi-quantitative method for prioritising each population of interest so as to allow an orderly progression of successive risk analyses based on each population's priority ranking is presented. Part 3 is an example evaluation of risk analysis for managing the threat of exotic disease to indigenous parrots (psittacines). Part 4 recommends the use of risk analysis as a standard and appropriate tool for the management of risk of exotic disease to indigenous fauna in New Zealand. The report recommends a number of actions that the Department of Conservation could make to reduce risk of exotic disease to indigenous psittacines in particular and indigenous fauna in general.
Humpback whales around New Zealand

The number of humpback sightings and the number of whales recorded in this study suggest a slow increase over the last 10 years, particularly in the last 4 years. The results of this study may have been influenced by a variety of factors, the most important of which may be inconsistent effort. The results presented in this report are broadly consistent with that described by Dawbin (1956). As reported by Dawbin (1956), and found in this study, the northern migration occurs between May and August while the southern occurs from September to December. There is little evidence of a change in migration patterns past the New Zealand coast. The inability to quantify effort is a major limitation with the data and does not make it possible to draw clear conclusions on population size or trends in migration. However, the results are useful in determining the locality and seasonality of humpback whales as they migrate along New Zealand coasts.
What's happening with stoat research? Report on the five-year stoat research programme
BRB

2000
In the May 1999 budget, the New Zealand Government announced that an extra $6.6 million over five years would be given to the Department of Conservation to fund an integrated stoat control research programme. Stoats, ferrets and weasels were introduced to New Zealand in the 1880s in an attempt to control rabbits. Although stoats were implicated in the decline of some native bird species soon after their introduction, the extent to which they are still contributing to the decline of native species is only now becoming clear. Their impacts on threatened and endangered birds are of particular concern. Stoat control in New Zealand will have to be ongoing if some endemic species are to survive on the mainland. Currently, stoat control relies largely on labour-intensive trapping and the use of poisoned hen eggs. New, more cost-effective and sustainable approaches to controlling stoats are urgently needed. The extra funding means that there is now a real opportunity for finding cost-effective solutions for managing stoats. A Stoat Technical Advisory Group (composed of experts from the Department of Conservation, Lincoln University and Auckland University) has been established to develop and oversee this new research programme. Funding for the first year is $338,000 with funding increasing in 2000/01 to $1.406 million and for the subsequent three years, $1.631 million, each year.
Autopsy report for seabirds killed and returned from New Zeland fisheries 1 January 1998 to 30 September - Birds returned by Ministry of Fisheries observers to the Museum of New Zealand Te Papa Tongarewa
Available Online

Robertson, C.J.R.

2000
There were 195 specimens returned from 19 separate fishing trips with onboard observers, between 1 January and 30 September 1998, where birds were killed as a bycatch to various forms of fishing practice. Four of these trips contributed 82% of the birds returned. These autopsies were undertaken for the Department of Conservation as CSL Contract 98/3091. All costs of labelling and packaging, importation under the Biosecurity Act, transportation from Port of Landing to Wellington by refrigerated truck, cold storage, and autopsy facilities were met by the Conservation Services Levy. In 1998 these birds were received from trawlers, domestic tuna longliners, joint venture tuna longliners, and domestic bottom longliners (Tables 1-4). The number of specimens returned for autopsy does not in any way indicate probable catch rates for differing classes of vessel or fishing method, as the observer coverage was not equally distributed throughout the fishing effort. Specific catch locations for the specimens returned are not provided here on the grounds of commercial sensitivity as required by the Ministry of Fisheries and some parts of the fishing industry. However, the maps (Figures 1-5) provide the general location of catches and species returned for the period covered by this report. The distribution shown does not imply any relationship with fishing effort or method as indicated above.
Conservation of kakerori (Pomarea dimidiata) : report on a visit to Rarotonga, August/September 1999 / Hugh A.

Robertson, Hugh Alexander

Since 1987, I have assisted the Cook Islands Conservation/Environment Service and, more recently, the Takitumu Conservation Area Project and the Avifauna Conservation Programme of the South Pacific Regional Environment Programme (SPREP) to plan and implement a recovery programme for the kakerori, a critically endangered forest bird endemic to Rarotonga. In 1989, the kakerori was one of the 10 rarest birds in the world, and classified as 'critically endangered' (Collar et al. 1994) with a population of just 29 birds. I calculated that there was a 50% chance of kakerori becoming extinct by 1998 unless nest predation by rats was significantly reduced. During each breeding season since 1989, rats have been poisoned in the 155 ha of forest occupied by kakerori (Robertson et al. 1998) and the effectiveness of this work has been measured by- recording breeding productivity (Saul et al. 1998), and by undertaking an annual census the following spring (Robertson 1998, 1999).
