  • Unsettling a Settler Family's History in Aotearoa New Zealand
    genealogy Article A Tale of Two Stories: Unsettling a Settler Family’s History in Aotearoa New Zealand Richard Shaw Politics Programme, Massey University, PB 11 222 Palmerston North, New Zealand; [email protected]; Tel.: +64-27609-8603 Abstract: On the morning of the 5 November 1881, my great-grandfather stood alongside 1588 other military men, waiting to commence the invasion of Parihaka pa,¯ home to the great pacifist leaders Te Whiti o Rongomai and Tohu Kakahi¯ and their people. Having contributed to the military campaign against the pa,¯ he returned some years later as part of the agricultural campaign to complete the alienation of Taranaki iwi from their land in Aotearoa New Zealand. None of this detail appears in any of the stories I was raised with. I grew up Pakeh¯ a¯ (i.e., a descendant of people who came to Aotearoa from Europe as part of the process of colonisation) and so my stories tend to conform to orthodox settler narratives of ‘success, inevitability, and rights of belonging’. This article is an attempt to right that wrong. In it, I draw on insights from the critical family history literature to explain the nature, purposes and effects of the (non)narration of my great-grandfather’s participation in the military invasion of Parihaka in late 1881. On the basis of a more historically comprehensive and contextualised account of the acquisition of three family farms, I also explore how the control of land taken from others underpinned the creation of new settler subjectivities and created various forms of privilege that have flowed down through the generations.

Sanderson c a Marine Sciences Research Center, State University of New York, Stony Brook, NY 11794, USA. b Physics Department, University of Auckland, Auckland, New Zealand. c Department of Oceanography, University of British Columbia, Vancouver, B.C., Canada. Received 9/8/82, in revised form 2/5/83, accepted 6/5/83. ABSTRACT The shelf seas of Central New Zealand are strongly influenced by both wind and tidally driven circulation and mixing. The region is characterized by sudden and large variations in bathymetry; winds are highly variable and often intense. Cook Strait canyon is a mixing basin for waters of both subtropical and subantarctic origins. During weak winds, patterns of summer stratification and the loci of tidal mixing fronts correlate weil with the h/u3 stratification index. Under increasing wind stress, these prevailing patterns are easily upset, particularly for winds b1owing to the southeasterly quarter. Under such conditions, slope currents develop along the North Island west coast which eject warm, nutrient depleted subtropical water into the surface layers of the Strait. Coastal upwelling occurs on the flanks of Cook Strait canyon in the southeastern approaches. Under storm force winds to the south and southeast, intensifying transport through the Strait leads to increased upwelling of subsurface water occupying Cook Strait canyon at depth.

  • Taranaki-Whanganui Conservation Board Notice of Appeal
    To The ReGistrar of the HiGh Court at WellinGton and To The Respondent and To The Applicant and To Other submitters This document notifies you that: 1 The appellant, being the Taranaki-WhanGanui Conservation Board (Conservation Board), will move the HiGh Court at WellinGton by way of appeal against the decision of the majority decision of the decision making committee of the Environmental Protection Authority (DMC), dated 3 AuGust 2017, public notice #EEZ000011, in which a marine consent and marine discharge consent was granted to Trans-Tasman Resources Limited (TTRL). The Application and Decision 2 TTRL applied for marine consents and marine discharge consents to enable it to mine iron sands in the South Taranaki BiGht, 22-36km offshore (Application). Up to 50 million tonnes of seabed material could be mined and processed each year, for up to 35 years. 3 The Environmental Protection Authority (EPA) made its decision on the application through its DMC (Decision). The DMC’s Decision was split. Two of the DMC’s members considered that the consents should be refused. They took the view that: … overall the localised adverse environmental effects on the Patea Shoals and tangata whenua existing interests are unacceptable, and are not avoided, remedied or mitigated by the conditions imposed. We also have concerns reGardinG uncertainty and the adequacy of environmental protection within the coastal marine area (CMA).1 4 However, the Chair held the castinG vote, and exercised it in favour of granting consent. Accordingly, the “majority decision” was to grant consent. 5 The DMC made its Decision on 3 August 2017.

  • Retrieval of Suspended Sediment Concentration in Near-Shore Coastal Waters Using MODIS Data

The thesis may not be reproduced elsewhere without the permission of the Author. Retrieval of suspended sediment concentration in near-shore coastal waters using MODIS data A thesis presented in partial fulfilment of the requirements for the degree of Master of Philosophy In Earth Science At Massey University, Palmerston North New Zealand Di Zhou 2012 1 Abstract: This study focuses on using remote sensing satellite data to retrieve water suspended sediment concentration (SSC) of near-shore coastal waters. Aqua/Terra Satellite MODIS 250m data of the south-western coast of the North Island, New Zealand was used. Two methods of analysis are used in this study to obtain an SSC map; non-liner optimisation and quasi-analytical. The non-linear optimisation method was used to fit an exponential function between reflectance and SSC, with SSC replaced by a linear relationship between SSC and reflectance in the near infrared domain. The optimisation result was used to convert Aqua/Terra MODIS images to SSC maps. The quasi-analytical method, a backscattering coefficient at 645nm is first derived from Aqua/Terra MODIS 250m Band 1 data using a quasi-analytical algorithm after applying a simple atmospheric correction routine. An empirical relationship was derived from laboratory experiments. Finally SSC maps were obtained by applying the empirical relationship to convert the backscattering coefficient to SSC. 2 Acknowledgements I would firstly like to thank my supervisor Mike Tuohy for his time and thoughtful advice throughout the preparation of this thesis.

  • Seabed Mining (KASM), Posted a Facebook Page Inviting People to Turn up at the Stadium When Hearings Began
    MINING MINEFIELD A company called Trans-Tasman Resources is having a second go at setting up a world-first project to mine iron ore from the seabed off South Taranaki’s coast. The company (TTR) has spent a decade and about $70 million to hone its case for Environmental Protection Authority (EPA) consent to take more than a billion tonnes of iron- bearing sand off the sea floor over 25 or so years. The process – which will return 90 percent of what’s extracted back to the seabed - will bring in about $400 million a year in off-shore ore sales, with our government getting about $6 million in annual royalties. The project is expected to increase Taranaki’s gross domestic product by about $220 million a year (half that of Methanex) and create about 300 jobs. Sound like a good deal? Somewhere between 13,733 and about 17,000 people (the total is disputed) don’t think so. Many people living in South Taranaki and further afield, local iwi, most of the fishing industry, and a close-neighbour oil company are worried about what it might do to the environment and local communities. That uncertainty has prompted their representative organisations and many individuals to fight the company to the bitter end. The case will be a precedent-setter under the Exclusive Economic Zone (EEZ) Act. Environmentalists don’t like the law, partly because it excludes climate change-causing emissions as grounds for objection, and partly because they reckon it’s the National government’s way of opening up our 200 kilometre-wide continental shelf to big overseas business.
