  • Auckland Regional Office of Archives New Zealand
    A supplementary finding-aid to the archives relating to Maori Schools held in the Auckland Regional Office of Archives New Zealand MAORI SCHOOL RECORDS, 1879-1969 Archives New Zealand Auckland holds records relating to approximately 449 Maori Schools, which were transferred by the Department of Education. These schools cover the whole of New Zealand. In 1969 the Maori Schools were integrated into the State System. Since then some of the former Maori schools have transferred their records to Archives New Zealand Auckland. Building and Site Files (series 1001) For most schools we hold a Building and Site file. These usually give information on: • the acquisition of land, specifications for the school or teacher’s residence, sometimes a plan. • letters and petitions to the Education Department requesting a school, providing lists of families’ names and ages of children in the local community who would attend a school. (Sometimes the school was never built, or it was some years before the Department agreed to the establishment of a school in the area). The files may also contain other information such as: • initial Inspector’s reports on the pupils and the teacher, and standard of buildings and grounds; • correspondence from the teachers, Education Department and members of the school committee or community; • pre-1920 lists of students’ names may be included. There are no Building and Site files for Church/private Maori schools as those organisations usually erected, paid for and maintained the buildings themselves. Admission Registers (series 1004) provide details such as: - Name of pupil - Date enrolled - Date of birth - Name of parent or guardian - Address - Previous school attended - Years/classes attended - Last date of attendance - Next school or destination Attendance Returns (series 1001 and 1006) provide: - Name of pupil - Age in years and months - Sometimes number of days attended at time of Return Log Books (series 1003) Written by the Head Teacher/Sole Teacher this daily diary includes important events and various activities held at the school.

  • Identifying Freshwater Ecosystems of National Importance for Biodiversity
    52 This unit encompasses the area south of a line running from Cape Rodney in the east to the northern side of the Waitakere Range, while its southern boundary extends eastwards from Port Waikato along the northern boundary of the Waikato catchment to include the Hunua Range and small catchments draining into the western shores of the Firth of Thames. The unit includes numerous offshore islands including Kawau, Tiritiri Matangi, Rangitoto, Motutapu, Waiheke and Ponui (Leathwick et al. 2003). Volcanism has had an intermittent influence during the Pleistocene, with Chadderton et al. —Creating a candidate list of Rivers of National Importance localised basaltic eruptions around Auckland, the most recent occurring about 500 years ago (Briggs et al. 1994). In addition, the neck of low-lying land between Manukau and Waitemata Harbours has been inundated during periods of sea level rise, and has probably acted as a barrier to dispersal of some organisms. Volcanic activity in Southern Auckland and Waitakere Ranges is considerably older (Leathwick et al. 2003). McLellan (1990) describes marked differences in stonefly assemblages between Auckland and Northland. Population-genetic differences have been recorded between individuals of three species collected in Northland compared to samples collected at sites further south, including around Auckland and/or in the Waikato (Smith & Collier 2001; Hogg et al. 2002; P. Smith pers. comm.). Auckland is also the northern limit for the giant kokopu. Auckland Catchment Name Type Heritage Euclidean Total REC

  • Whanganui River and Te Urewera Treaty Settlements: Innovative Developments for the Practice of Rangatiratanga in Resource Management
    Whanganui River and Te Urewera Treaty Settlements: Innovative developments for the practice of rangatiratanga in resource management By Stephanie Warren A thesis submitted to Victoria University of Wellington in fulfilment of the requirements for the degree of Master of New Zealand Studies. Victoria University of Wellington 2016 Abstract This thesis concerns the recent innovative developments in the Whanganui River and Te Urewera Treaty settlements of 2014. The Whanganui River has become the first specific environmental resource to receive the rights and status of a legal person. Te Urewera has been removed from the 1980 National Parks Act to also become its own legal person. Both legal personalities will be co-managed by boards of equal Crown and iwi members. The Te Urewera Board will, however, be rearranged in 2018 to have a Tūhoe majority, another first for Treaty of Waitangi settlements. These new features are considered particularly innovative in this thesis because of the context of Crown indivisible sovereignty and its unequal share of power in negotiating settlements. This thesis considers the ability of these settlements to provide space for iwi to practice rangatiratanga in relation to the resource that is central to their history and identity. If rangatiratanga is considered in this context to be the ability of iwi to practice self-determination and autonomy, then these settlements go further than previously seen because the application of the legal personality and the way it is co-managed is based for the most part on the worldview of the iwi. However, this worldview will continue to be practiced within the wider context of the English political and legal system.

Many of the streams visited were accessible only through private land, and could only be accessed with the help and cooperation of landowners throughout the area. Funding for this work came from Rob Donald, Manager of the Science Team, Bay of Plenty Regional Council. Environmental Publication 2016/12 – Fisheries assessment of waterways throughout the Rangitāiki WMA i Dedication This report is dedicated to Geoff Burton, who was tragically taken from us too soon whilst out running near Opotiki. Although Geoff had connections to Ngati Maniapoto (Ngati Ngutu) and was born in the Waikato, he moved with his wife and children back to Torere in the early 2000s to be closer to her whanau. Geoff had been a board member of Te Kura o Torere and was also a gazetted Ngaitai kaitiaki. He was completing studies at Te Whare Wānanga o Awanuiārangi where he was studying Te Ahu o Taiao. It was during this time that his supervisors recommended Geoff to assist with the fish survey work described in this report.

Purpose The purpose of the Rangitāiki River Catchment programme is to coordinate Bay of Plenty Regional Council work, including work required for Te Ara Whānui o Rangitāiki – Pathways of the Rangitāiki, to deliver on community expectations. The work programme covers all significant activities in the river catchment, including work across policy and planning, science, pollution prevention and maritime service functions. It also includes all operational activities such as biosecurity, biodiversity protection, coast care, rivers and drainage, and sustainable land management. The programme covers all significant activities (both projects and ongoing work) in the river catchment area carried out by Regional Council. The programme is broken into five areas of focus and presented in the following sections: • Te Ara Whānui O Rangitāiki – Pathways of the Rangitāiki • Governance and programme management • Integrated planning • Science • Operations 2. Background Council does not have a specific vision or outcomes for the catchment but the Rangitāiki River Forum of which we are a partner does in Te Ara Whānui O Rangitāiki (Te Ara Whānui o Rangitāiki) – Pathways of the Rangitāiki, and they are entirely suitable.

  • Rangitaiki - Tarawera Rivers Scheme Asset Management Plan
    E NVIR ONMENT B. O .P Environment B·O·P Operations Report 98/03 September 1998 Bay of Plenty Regional Council RANGITAIKI - TARAWERA RIVERS SCHEME ASSET MANAGEMENT PLAN Report prepared by Philip Wallace, Technical Services Section Environment B·O·P Quay Street P O Box 364 Whakatane NEW ZEALAND ISSN 1173 - 6232 Environment B·O·P Foreword This plan is a statement by Environment B·O·P, the Manager of the Rangitaiki–Tarawera Rivers Scheme, as to how it will manage the assets of that scheme. The plan represents prudent management as required by the Local Government Amendment Act (No.3) 1996. The plan was adopted by the Council during April 1998 following liaison and consultation, in particular with the scheme ratepayers. Cover Photo: Rangitaiki River Mouth Operations Report 98/03 q:\mas\ors\docs\Rangitaiki-Tarawera Asset Mgmt Plan Environment B·O·P i Executive Summary The purpose of this plan is to provide a document for the management of the Rangitaiki– Tarawera Rivers Scheme and in particular its infrastructural assets. It establishes and communicates the level of funding required to maintain and meet the scheme objectives and levels of service. The plan covers the assets of the scheme including stopbanks, floodgates, pump stations, rockwork and other erosion protection measures, and plantings. The current valuation at September 1996 (in terms of Local Government Act requirements) of these assets is $22.5 million. The assets are generally in good condition and with existing maintenance programmes are providing the desired levels of service, although previous diversion of maintenance funds to flood damage repairs has compromised riverbank edge protection.
