title: Faunal extinction and human habitation in New Caledonia: Initial results and implications of new research at the Pindai Caves

authors: Anderson, Atholl

subjects: New Caledonia

abstract: Archaeological and palaeontological investigations occurred in 2003 at the Pindai Caves in New Caledonia, where remains of prehistoric settlement exist in conjunction with the richest fossil deposits found to date on Grand Terre. Among more than 45 bird taxa in our excavations at least 20 that are locally or globally extinct are represented at levels immediately below or within the era of human occupation. These include the giant megapode, Sylviornis sp., the flightless swamphen, Porphyrio kukuwiedei, and other rails, a kagu, pigeons, a large snipe, Coenocorypha sp., several taxa of owls, a nightjar, and an owlet-nightjar. Unresolved problems in dating and taphonomy, however, make it difficult to specify the strength of cultural associations and thus the extent to which human activities were responsible for extinctions or extirpations. We present the first radiocarbon dates upon Sylviornis bone, showing that, at least, the species survived into the late Holocene. Relatively frequent occurrence of Sylviornis bone in the cultural levels, coupled with a radiocarbon date on a bone sample of about 3000 calBP make a case for human contact.

title: Acetylene reduction associated with zostera novazelandica Setch. and Spartina alterniflora Loisel., in Whangateau harbour, North Island, New Zealand

authors: Hicks, Brendan J.

subjects: biology

abstract: Nitrogen fixation (acetylene reduction) was investigated in Zostera novazelandica Setch. and Spartina alterniflora Loisel., in the North Island of New Zealand. Moderate rates of acetylene reduction were found in sediments in which plants were growing (means ± 95% confidence limit: 15.2 ± 2.8 |jmol C2H4 nrr2 h~l for Zostera and 24.7 ± 4.6 |amol C2H4 m~2 h"1 for Spartina). Activity was closely correlated with the dry weight of root; (r2 = 0.65, N = 15 for Zostera, and r2 = 0.85, A' =10 for Spartina). Sediment close to the plant beds, but without plants, exhibited only low rates of acetylene reduction (2.9 ± 2.2 and 4.5 ± l.OjLtmol C2H4 m~2 h"1, respectively). Sediments associated with Z. novazelandica and S. alterniflora in New Zealand exhibit moderate rates of nitrogenase activity compared to rates found in other countries. N fixation may contribute significantly to the nutrition of these plants in New Zealand estuaries.

title: Health reform and the impact on Mäori 1983-1997

authors: Ferguson, Lisa Arleen.

abstract: This study investigates the New Zealand health sector reforms from 1983 to 1997and examines whether the reform process has been consistent with the principles of the Treaty of Waitangi. It evaluates the impact of the reforms on Mäori from that perspective. 

The study introduces the health sector reforms generally and then their specific effects on Mäori. It draws on two research exercises undertaken by the author, being research for the Wai 692 Napier Hospital and Health Services claim to the Waitangi Tribunal and on improving Mäori Health outcomes for the National Health Committee. The methodologies used are those from the discipline of history.

The study outlines the argument for Crown responsibilities under the Treaty and draws out the distinctions between Article 2 and Article 3 of the Treaty. It provides a historical background to the place of the Treaty in the health sector, and forms the basis for a Treaty based analysis of the health reforms and their impact. 

The New Zealand health sector has undergone massive government initiated structural change throughout the period under study. During this time the neo-liberal reforms have had a key role in reshaping health service structures. The process of change, the international influences on the changes, and the resulting entities are described. An example from Tainui Iwi of the effect of structural health reform illustrates the changes in Mäori health service provision by Mäori.
Since 1983 successive governments have produced copious Mäori health policy. The key policy documents, and their recommendations, are identified, as is the degree to which they were implemented. The cyclical nature of such policy making suggests that it is not always followed by policy implementation. While Mäori are identified as a health gain priority, the evidence reviewed shows that the responsibility to implement and monitor the policy is diffuse and ineffective.

The Wai 692 claim provides a detailed look at the impact of the 1990s health reform for Mäori. The claim was precipitated by the threatened closure of Napier Hospital, but was broadened to include a wide-ranging look at the impact of health reform on Mäori. As a case study it provides a specific example of one Iwi’s experience of the reality of policy implementation at that time versus policy making.

Crown evaluation of the effectiveness of its own policies, and the extent to which its own agencies breach those policies is explored. The lack of control and accountability measures, plus the inability of the Crown to monitor (let alone sanction) success or failure, is highlighted. A contrast is drawn between the health and local government sectors, using the operation of the Resource Management Act (1991). 

The latest health sector reforms consequent on the 1999 Labour/Alliance coalition government are briefly considered, together with an overview of the Crown’s effectiveness in delivering improved Mäori health outcomes. The study suggests that the use of the Treaty as a cornerstone for Maori health policy formation and delivery may lead to more effective engagement between the Crown and Mäori in addressing Mäori health issues. The study concludes by asking the question, has the health sector reform process of the 1980s and 1990s itself been a Treaty breach?

A brief postscript considers the further reform of the health sector beyond the period of study.
