title: Growth and magmatic evolution of Tongariro and Raupehu volcanoes, New Zealand

authors: Hobden, Barbara J.

abstract: The aim of this excursion is to examine new work on the eruptive and magmatic histories of Tongariro and Ruapehu Volcanoes. By integrating geochemical and isotopic analyses within a well-constrained framework of geochronology and volcanic stratigraphy, our studies have shown that growth of these andesite cone volcanoes involves multiple small batches of magma whose compositions are strongly modified in complex, probably polybaric plumbing systems on time scales as short as a year. Rapid production and ascent of magma is a characteristic of the Quaternary history of both the silicic and andesitic portions of Taupo Volcanic Zone (TVZ). Central TVZ is dominated by two exceptionally active rhyolitic calderas, Okataina and Taupo, while the landscape of the southem TVZ is dominated by two highly active composite volcanoes, Tonga1iro and Ruapehu. There are strong similarities between Tongariro and Ruapehu (compare for example Hobden et al., 1999 with Gamble et al., 1999).

title: The mechanisms of subnational population growth and decline in New Zealand 1976-2013

authors: Jackson, Natalie

abstract: This article summarises key findings from the strand of the Tai Timu Tangata. Taihoa e? project that examined the mechanisms of subnational population change in New Zealand for 143 towns, 132 rural centres and 66 territorial authority areas (hereafter TAs), for the 37-year period 1976-2013. Because of space constraints we present the information as a set of 10 summary observations. For the underlying analyses please refer to Jackson, Brabyn and Maré (2016); Jackson and Cameron (2017), Jackson, Brabyn, Maré, Cameron and Pool (forthcoming); and Jackson and Brabyn (forthcoming).

title: Te Aka Roa o Te Oranga, the far reaching vines of wellness: The development of a framework to evaluate alcohol and drug treatment for Māori

authors: Robertson, Paul

subjects: Maori

abstract: The impact of alcohol and other drug
problems for Māori is well documented.
Substance use has been implicated in a
range of physical and mental health
problems, and a variety of negative social
statistics such as high rates of imprisonment. To date there has been
little systematic documentation of treatment
practices, and limited operationalisation of
Māori health frameworks. The evaluation
of the outcomes of alcohol and other drug
treatments is an area in which there is a
paucity of documentation, in terms of
methods and frameworks for evaluation,
and actual data. Te Aka Roa O Te Oranga (TAROTO)
was developed from a range of projects
undertaken by the National Addiction
Centre. The TARATO evaluation framework
embraces a holistic perspective: developed
to examine the interaction between the
client, whānau, practitioner, and
service/organisation. The aim of the
framework is to clarify the complex
relationships and interactions between
stakeholders within the context of
treatment. It will also help to elucidate the
strengths and weaknesses of individual
services. Within this framework, a range of
indicators and outcomes of “successful
treatment” will be explored. The current project is the first phase of
a broader project that will make a
significant contribution to improvements in
Māori health via further developing
effective treatments of alcohol and other
drug related problems.
