SummaryIntroduced mammalian predators have been implicated in the majority of avian extinctions on oceanic islands around the globe. Nowhere is this more apparent than in the decimated New Zealand avifauna, where introduced predators remain the primary threat to virtually all surviving endemic species, including the threatened New Zealand Falcon Falco novaeseelandiae. We used remote videography at falcon nests and conducted an artificial nest experiment to compare the rates of predation and responsible predators of falcons nesting in hills against those nesting in nearby commercial vineyards. Overall, 63% of artificial nests in the hills were predated, compared with 38% in vineyards. Further, artificial eggs were predated faster in the hills than those placed in vineyards. Video footage revealed that the suite of predators visiting real falcon nests was similar to those identified attacking artificial nests. However, predators differed across habitats, with nests in vineyards being predated mainly by hedgehogs Erinaceus europaeus and Australasian Harriers Circus approximans, whereas nests in the hill environments were mainly attacked by stoats Mustela erminea. These results demonstrate the important implications of habitat type on predation pressure associated with introduced predators. These may well prove a fruitful avenue of management if breeding can be fostered in safer areas, as in the case of this threatened falcon.

We tracked two adult and three juvenile New Zealand falcons (Falco novaeseelandiae) in Kaingaroa Forest pine plantation from 2002 to 2008 using Argos satellite technology. The home ranges for both adults and juveniles varied, ranging between 44 and 587 km2. The falcons occasionally utilised areas outside the forest and used stands of all ages within the forest, generally in proportion to their availability. For the most part, the juveniles remained within ca. 8 km of their nests and dispersed at 58, 69, and 68 days after fledging. Falcon movement information was obtained from an average of four location points per tracking day per falcon at a putative accuracy of 350 m. The transmitters, including their solar charge capability, performed well in the forest environment. The use of all stand ages highlights the importance of forestry practises that maintain a mosaic of different aged pine stands.

Context The risk of secondary poisoning to native fauna during pest control operations is an issue of global concern. In New Zealand, non-target impacts during sodium fluoroacetate (1080) operations are particularly contentious. 1080 is used extensively for pest control for conservation, bovine tuberculosis control, and in plantation forestry for seedling protection from herbivores. The endemic New Zealand falcon (Falco novaeseelandiae) breeds in Kaingaroa forest, an intensively managed pine plantation where regular 1080 poison operations are conducted; however, causes of mortality and risks of secondary poisoning by 1080 are not well documented. Aims We aimed to investigate mortality and survival of adult falcons with an emphasis on assessing the possible role of 1080 poisoning in annual mortality. Methods Using radio-telemetry and visual observations, we monitored 37 marked adult falcons before and after 1080 operations in 2013–14 (16 through carrot-bait and 21 through cereal-bait operations) and assessed mortality causes through post-mortem examinations. Using Program MARK, the annual survival rates for adults and independent juveniles were estimated from long-term banding data (2003–2014). Key results Survival of falcons was high through both cereal-bait (21/21) and carrot-bait (15/16) 1080 operations (overall 95% CI for survival = 84–100%). The exception was a radio-tagged male that died of unknown causes within a fortnight of an operation and tested negative for 1080 residues. Three falcons were depredated by introduced mammals. One falcon was found dead in an emaciated condition but evidently died from head injury through Australasian magpie (Cracticus tibicen) attack. The annual survival rate of falcons estimated from long-term banding was 80 ± 6.0% (mean ± s.e.) for adults and 29 ± 0.1% for juveniles. Conclusions No adult falcon death was attributable to 1080 poisoning in this study. Identifiable mortalities were attributable to depredation by introduced mammals and an injury from an Australasian magpie. The annual survival rate of Kaingaroa falcons was comparable to those of other raptor species worldwide. Implications The risk to adult falcons from 1080 secondary poisoning is likely low. Whether this is also true for juveniles requires further study.

Alf Howard, (Fig. 1) died on 4 July 2010. He was the last surviving member of Sir Douglas Mawson's 1929–1931 British, Australian and New Zealand Antarctic Research Expedition (BANZARE) that made further extensive claims to sovereignty defining the limits of what was to become Australian Antarctic Territory (AAT) in 1933. He was also the last survivor to have served aboard the coal-fired three-masted wooden ship Discovery built in Dundee for Captain Robert Falcon Scott's 1901–1904 National Antarctic Expedition.

AbstractIn this paper a detailed record of major ions from a 20 m deep firn core from Amundsenisen, western Dronning Maud Land, Antarctica, is presented. The core was drilled at 75° S, 2° E (2900 m a.s.l.) during austral summer 1991/92. The following ions were measured at 3 cm resolution: Na+, Mg2+, Ca2+, Cl−, NO3−, S042− and CH3SO3H (MSA). The core was dated back to 1865 using a combination of chemical records and volcanic reference horizons. The volcanic eruptions identified in this core are Mount Ngauruhoe, New Zealand (1974–75), Mount Agung, Indonesia (1963), Azul, Argentina (1932), and a broad peak that corresponds in time toTarawera, New Zealand (1886), Falcon Island, South Shetlands, Southern Ocean (1885), and Krakatau, Indonesia (1883). There are no trends in any of the ion records, but the annual to decadal changes are large. The mean concentrations of the measured ions are in agreement with those from other high-altitude cores from the Antarctic plateau. At this core site there may be a correspondence between peaks in the MSA record and major El Niño–Southern Oscillation events.

In our ever more populated world, the rapid expansion and intensification of agriculture is driving worldwide biodiversity loss, and the interactions between production landscapes and wildlife conservation are becoming increasingly important. Farming systems depend on ecosystem services such as biological control, while conservationists are calling for the establishment of conservation initiatives in non-preserve landscapes. Despite this, the goals of agriculture and the goals of predator-conservation are rarely mutual. Here, I demonstrate one of the first examples of a mutually beneficial scenario between agriculture and predator conservation. I used, as a case study, a reintroduction project that translocated individuals of the threatened New Zealand falcon (Falco novaeseelandiae) from the hills of Marlborough into vineyards, to determine if predators can survive within an agricultural landscape while simultaneously providing that landscape with biological control services. Examples of vertebrates providing biological control to agriculture are rare. I show that the presence of falcons in vineyards caused an economically important reduction in grape damage worth over US $230/ ha. Falcon presence caused a 78- 83% reduction in the number of introduced European pest birds, which resulted in a 95% reduction in the damage caused by these species. Falcon presence did not cause a reduction in the abundance of the native silvereye (Zosterops lateralis), but did halve the damage caused by this species. To assess the conservation value of the falcon translocations, I used remote videography, direct observations and prey analysis to measure the behavioural changes associated with the relocation of falcons from their natural habitat in the hills and into vineyards. Falcons in vineyard nests had higher nest attendance, higher brooding rates, and higher feeding rates than falcons in hill nests. Additionally, parents in vineyard nests fed their chicks a greater amount of total prey and larger prey items compared to parents in hill nests. I also found an absence of any significant diet differences between falcons in hill and vineyard habitats, suggesting that the latter may be a suitable alternative habitat for falcons. Because reintroduced juvenile falcons were released in areas devoid of adult falcons, it was possible that they were missing essential training normally provided by their parents. I used direct observations to demonstrate that the presence of siblings had similar effects to the presence of parents on the development of juvenile behaviour, with individuals flying, hunting, and playing more often when conspecifics were present. Finally, through the use of artificial nests and remote videography, I identified that falcons nesting in vineyards are likely to suffer lower predation rates. I also found that falcons in vineyards are predated by a less dangerous suite of animals (such as hedgehogs, Erinaceus europaeus, and avian predators), than their counterparts in the hills, which are predated by more voracious species (such as stoats, Mustela erminea, and feral cats, Felis catus). The work presented in this thesis has also added to the current knowledge of New Zealand falcon breeding behaviour, prey preferences, and behavioural development. Although agricultural regions globally are rarely associated with raptor conservation, and the ability of raptors to control the pests of agricultural crops has not been previously quantified, these results suggest that translocating New Zealand falcons into vineyards has potential for both the conservation of this species, and for providing biological control services to agriculture

Then law governing vertical arrangements is a comparatively undeveloped area in NZ competition law. With only resale price maintenance (RPM) expressly prohibited by the Act, it has fallen to the general prohibitions on anticompetitive arrangements and monopolization to address traditional antitrust mischiefs such as exclusive dealing and tying. The leading case on exclusive dealing was heavily influenced by Chicagoan thinking to the degree that the courts gave the green light to durable distribution arrangements that countenanced foreclosure on a large scale and were plainly anti-competitive. However, the few cases on tying have been more fruitful insofar as remedies have been granted to rectify blatant leveraging by dominant firms into related markets. A period of active enforcement of RPM by the Commerce Commission marked the first decade, but the swathe of prosecutions dried up as the twenty-first century began.

Remembered songs of extinct wattlebirds, endemic to Aotearoa New Zealand, catalyze Julianne Warren's storytelling. In Chapter 2, she spins a path from first listening to a Pākehā-narrated recording of an elder Māori performing traditional mimicry of Huia. Replaying these dead bird-human voices interacting with sounds in the near-Arctic helps her begin learning, in poet W.S. Merwin’s words, to 'hear what never/Has fallen silent.' Between antipodes, ancestral echoes escape from machines, and sleeping languages live on—in loss—uncanny companionships of hope's sound.

Meeting the needs of people with co-existing mental health and addiction problems is a challenge faced by many mental health and addiction services and providers. A compounding factor has been the separation of mental health and addiction services which has meant that many people with co-existing mental health and addiction problems have fallen through the cracks between services or had issues not recognized or responded to, leading to poor health outcomes. This chapter describes the approach taken by New Zealand's workforce development centers to support services to improve responsiveness and workforce capability to work with people with co-existing mental health and addiction problems. International research on implementation is briefly summarized before discussion about the impact of the national approach and the barriers to implementation that have emerged. Recommendations for next steps conclude this chapter.

Information and communications technologies (ICTs) are playing an increasingly vital role in the daily lives of all communities by revolutionizing their working procedures and rules of governance. ICTs offer a unique opportunity for governing elite to overcome the crisis of representative democracy, as ICT and the Internet empower civil society to play its role more effectively and facilitate the performance of governments’ main function-serving the people who elect them (Misnikov, 2003). In the realm of government, ICT applications are promising to enhance the delivery of public goods and services to common people not only by improving the process and management of government, but also by redefining the age-old traditional concepts. Community networking groups and local government authorities are well placed to campaign for greater inclusion for all members of the community in the information society. Possible areas to target include the provision of technology at low or no cost to groups through community technology centres or out of hours school access. There are many possibilities and local government must take a significant role in these activities (Young, 2000). Information society is based on the effective use and easy access of information and knowledge, while ICT for development (or ICTD) is not restricted to technology itself but focusing on manifold development and diverse manifestations for the people to improve their well-being. ICTD has deep roots in governance, is part of governance and has effects on governance patters and practices at both central and local level. By recognizing these facts, UNDP focuses on technologies to end poverty at WSIS Cyber Summit 2003, and emphasizes on ways that new technologies can help lift more than one billion people out of extreme poverty (UNDP, 2003). Apart from the four Asian IT giants (Korea, Rep., Hong Kong, China, Taiwan, China, and Japan), most of the Asian countries have fallen under the “low access” category of the Digital Access Index. This has also been referred in the WSIS Cyber Summit 2003, until now, limited infrastructure has often been regarded as the main barrier to bridging the digital divide (ITU, 2003). Among the countries with ICT spending as share of their GDP, Sweden, UK, The Netherlands, Denmark, and France (8.63, 7.97, 7.39, 7.19, and 6.57% respectively during 1992-2001) remain at the top (Daveri, 2002, p. 9), while countries like Bangladesh, Greece, Mexico, Niger, and many more remain at the bottom (EC, 2001; ITU, 2003b; Miller, 2001; Piatkowski, 2002). In a similar research it has been found that in terms of average share of ICT spending GDP, New Zealand, Sweden, Australia, USA, and UK (9.3, 8.4, 8.1, 8.1, and 7.8% respectively during 1992-1999) were among the highest (Pohjola, 2002, p. 7), though most of the countries in the Asian and African regions remain below the average of 5%. The disadvantaged communities in the countries staying below average in ICT spending seem to be lagging in forming appropriate information-based economy and eventually fall behind in achieving proper e-government system. The e-government system in those countries need to enhance access to and delivery of government services to benefit people, help strengthen government’s drive toward effective governance and increased transparency, and better management of the country’s social and economic resources for development. The key to e-government is the establishment of a long-term dynamic strategy to fulfill the citizen needs by transforming internal operations. E-government should result in the efficiency and swift delivery and services to citizens, business, government employees and agencies. For citizens and businesses, e-government seems the simplification of procedures and streamlining of different approval processes, while for government employees and agencies, it means the facilitation of cross-agency coordination and collaboration to ensure appropriate and timely decision-making. Thus, e-government demands transformation of government procedures and redefining the process of working with people and activities relating to people. The outcome would be a societal, organizational, and technological change for the government and to its people, with IT as an enabling factor. E-government should concentrate on more efficient delivery of public services, better management of financial, human and public resources and goods at all levels of government, in particular at local level, under conditions of sustainability, participation, interoperability, increased effectiveness and transparency (EU, 2002). ICT brings pertinent sides more closely by prioritizing partnerships between the state, business and civil society. A few East European countries have became economically liberal with the high level of foreign direct investment per capita and at the same time became ICT-advanced regional leaders in terms of economic reform. These countries also present the region’s most vivid examples of partnerships and collaboration. They have clearly manifested the importance of the public-private partnerships, transparent bottom-up strategies, involvement of all stakeholders, total governmental support, capturing economic opportunities, and enabling electronic mediated businesses, responding to the challenges of globalization.
