title: A matter of security, privacy and trust: A study of the principles and values of encryption in New Zealand

authors: Dizon, Michael

abstract: Cybersecurity is crucial for ensuring the safety and well-being of the general public, businesses, government, and the country as a whole. New Zealand has a reasonably comprehensive and well-grounded legal regime and strategy for dealing with cybersecurity matters. However, there is one area that deserves further attention and discussion – encryption. Encryption is at the heart of and underpins many of the technologies and technical processes used for computer and network security, but current laws and policies do not expressly cover this significant technology.
The principal objective of this study is to identify the principles and values of encryption in New Zealand with a view to informing future developments of encryptionrelated laws and policies. The overarching question is: What are the fundamental principles and values that apply to encryption? In order to answer this question, the study adopts an interdisciplinary approach that examines the technical, legal and social dimensions of encryption. With regard to the technical dimensions, this requires exploring the technical elements and aspects of encryption and how they can impact law and society. In relation to law, existing and proposed encryption law and policies in New Zealand and other jurisdictions are examined in terms of how they affect and are affected by encryption. On the social dimension, the perceptions, opinions and beliefs of three groups of stakeholders most concerned about encryption (i.e., the general public, businesses and government) are recognised and considered.

title: High diversity and local endemism in Aotearoa New Zealand's groundwater crustacean fauna

authors: Fenwick, Graham D.

subjects: Science & Technology

abstract: We used DNA barcoding to assess the diversity and distribution of New Zealand's groundwater amphipods and isopods (Crustacea) and to determine whether biodiversity and endemism within tectonically active New Zealand are similar to those of more tectonically stable continents. Sixty-five wells were sampled in seven aquifers across four regions within the North and South islands of New Zealand, and resident invertebrates were morphologically identified and then assessed using sequencing of the mitochondrial DNA cytochrome c oxidase subunit one (COI) gene. Invertebrates were found in 54 wells. Of the 228 individual amphipods and isopods found in 36 of the wells, 154 individuals were successfully sequenced for COI (68% success rate) from 25 wells, with at least one well in each aquifer containing sequenced individuals. Of the 45 putative species identified using Barcode Index Numbers (BINs), 30 BINs (78% of all taxa and 83% of amphipods) were previously unrecorded. Substantial morphologically cryptic, species-level diversity was revealed, particularly within the amphipod Family Paraleptamphopidae. Similarly, one isopod taxon morphologically identified as Cruregens fontanus was assigned to five well-separated BINs based on COI sequences. Endemism appeared high, with all taxa regionally endemic; 87% of species were restricted to one aquifer and more than 50% restricted to one well. Non-saturated species accumulation curves indicated that, while additional sampling may increase the range of some currently identified taxa, additional range-restricted taxa are also likely to be discovered. Patterns of diversity and short-range endemism were similar to those found elsewhere, including locations which are more tectonically stable. The predominance of local endemism within New Zealand's groundwater fauna suggests that land-use activities and groundwater extraction require careful evaluation to minimize threats to groundwater biodiversity.

title: Empowerment evaluation of Te Taiwhenua o Heretaunga Family Start: Improving service delivery

authors: Little, Gaylene Robina

subjects: Family Start

abstract: This thesis explores child maltreatment in New Zealand by considering service delivery of the Family Start programme at Te Taiwhenua o Heretaunga through an empowerment evaluation. The purpose of this research is to evaluate the service delivery process of the Family Start programme at this site to inform the organization and other Family Start key agents of possible improvements to service delivery so that the Family Start programme is best able to reduce the risk factors that are known to influence child maltreatment in New Zealand. The best possible service delivery by kaupapa providers supports sustainability and the continuity of service with Māori through continual funding. The two objectives of this research are to look at how well the Family Start programme is implemented at Te Taiwhenua o Heretaunga and to consider the cultural appropriateness of service delivery. Community psychology is the paradigm within which I position myself. I respect the values of community psychology that aim to improve the position of disadvantaged people through their participation in social change and community development. Te Taiwhenua o Heretaunga is a kaupapa Māori provider and I see an empowerment evaluation as a tool for internal evaluation to assist organizations who value self determination in their own practice. Both quantitative and qualitative data were collected and analyzed. There are two objectives to consider service delivery; firstly process aspects of service delivery are looked at and secondly the cultural relevance of service delivery to the population receiving the Family Start programme at this site. These are described as nine points about service delivery. The aim is to provide an empowerment evaluation for Te Taiwhenua o Heretaunga to inform, assist and improve service delivery of the Family Start programme in a culturally appropriate manner. The findings suggest better understanding is needed by Te Taiwhenua o Heretaunga Family Start staff, about the programme intentions, the use of tools such as Born to Learn/Ahuru Mōwai, individual family plans, service delivery levels, maintaining health records and ways to encourage collaboration between agencies. Te Taiwhenua o Heretaunga are shown in this research to be reaching the intended population for the Family Start programme, and service delivery appears to be culturally relevant to the clients on the programme at this time. The findings are limited by the fact that access to some information was restricted by Te Taiwhenua o Heretaunga Family Start management. Consequently, this research looked only at service delivery, and not the benefits of or barriers to the actual programme. The effectiveness of the programme in reducing child maltreatment is important but could not be measured in this research. Reducing child maltreatment is the main aim of the Family Start programme and would be measured through client outcomes. This research considered service delivery to see if the Family Start programme is offered optimally to assist the aim of reducing child maltreatment.
