Chatam Islands Chatham Islands Conservation Management Strategy AUGUST 1999 Chatham Islands Conservation Management Strategy August 1999 Published by: Department of Conservation PO Box 5086 Wellington New Zealand Wellington Conservancy Conservation Management Planning Series No. 8 ISSN 1172-9406 ISBN 0-478-21894-X © 1999, Department of Conservation Cover image from a photograph by C.J.R. Robertson Foreword The Chatham Islands environment is special; rich in its variety of indigenous plants and animals, historic relics and landscapes. Many of the plants and animals found at the Chatham Islands are unique and are found only there, making these islands particularly significant for conservation. The Chatham Island community has strong ties to its land and resources and a high awareness of conservation issues. Many of the islanders are actively involved in the guardianship of these natural and historic resources. The Chatham Islands Conservation Management Strategy (CMS) which was prepared in accordance with Part IIIA of the Conservation Act 1987, recognises the special significance of the Chatham Islands and the need for the Department to work closely with the island community in achieving conservation results. It sets out the management directions for the Department in the Chatham Islands over the next ten years. A conservation management strategy is a statutory document which implements general policies and establishes objectives for the integrated management of natural (including land and species) and historic resources. Its effects are quite important. Some activities on land administered by the Department can only take place by and in accordance with the conservation management strategy. Those preparing regional and district plans under the Resource Management Act must have regard to any relevant conservation management strategy. It must be noted however, that a CMS is generally a statement of intent and, although in itself a document having statutory backing, it does not override the provisions of legislation and general policy. This CMS has been prepared in consultation with the Chatham Island Conservation Board and was available for public comment from May to October 1996, with a total of 26 submissions received. Formal hearings before representatives of the Conservation Board and the Department were held for nine submitters who spoke in support of their submissions. All submissions received are summarised in a separate document. After considering all the submissions a summary of them was prepared and the draft CMS was revised. The revised draft CMS and a summary of the submissions were presented to the Chatham Island Conservation Board for its consideration. The Board requested further amendments to ensure that the document played due attention to public opinion as expressed through submissions and consultation. In March 1999 the Board submitted the CMS to the New Zealand Conservation Authority for approval. A committee of the Authority met the Board on Chatham Island and discussed relevant issues with Board members. The Authority consulted the Minister of Conservation and requested further amendments. The amendments were made and this Conservation Management Strategy was subsequently approved by the New Zealand Conservation Authority on 12 August 1999.

Introduction 1.1 HOW TO USE THIS DOCUMENT The Chatham Islands Conservation Management Strategy is a complex document. It can be studied by reading just those sections dealing with a specific place (see Part 5) or a specific issue (see Part 6). However, to get a fuller picture of the Department’s responsibilities, wider reading of the document is needed. The CMS contains seven major sections, setting out departmental management directions for the next ten years and schedules of the lands managed by the Department, which should be read in conjunction with Parts 1 to 7. 1.2 WHAT IS A CONSERVATION MANAGEMENT STRATEGY? Conservation Management Strategies (CMSs) are a statutory requirement of the Conservation Act 1987 and are being prepared for each of the 13 conservancies administered by the Department of Conservation in New Zealand.

  • Chatham Islands Museum News Issue No 2
    Chatham Islands Museum News Issue No 2 The focus over the last three months has been on the Concept Plan for the new museum received from the designer, Sally Papps, in October. This is an excellent document but is far too large to be put up on the website. Discussions on the content with imi, iwi and the broader community were held in early December and these resulted in some suggested revision of the entrance and flow of topics. Comments have been sent to Sally and the plan is under revision. A further round of discussions will be held once a revised document has been received and more detail on each section will be sought. A short version of the revised plan will be put up on the website to allow for wider consideration and comment. Staff and volunteers have been searching the museum’s photographic collection for interesting photographs relevant to each of the Concept Plan topics, listing these and adding thumbnails, so the final selection will be quicker and easier for Sally. Photographs held at the Alexander Turnbull Library are also being checked for relevance and interest. The museum’s application to Lottery Environment and Heritage was successful. This will enable the transferring of videos to USB and the editing of audio-visual excerpts for use in the new museum to proceed and also allow information for two touchscreens to be prepared. Hamish Campbell has agreed to prepare the geological history of the Islands and Jocelyn Powell will work with mapping experts to develop the coastal chart and land mapping history.

  • Memory Work on R ¯Ekohu (Chatham Islands) Kingsley Baird
    Memory Connection Volume 3 Number 1 © 2019 The Memory Waka Hokopanopano Ka Toi Moriori (Reigniting Moriori Arts): Memory Work on R ¯ekohu (Chatham Islands) Kingsley Baird Hokopanopano Ka Toi Moriori (Reigniting Moriori Arts): Memory Work on R ¯ekohu (Chatham Islands)—Kingsley Baird Hokopanopano Ka Toi Moriori (Reigniting Moriori Arts): Memory Work on R ¯ekohu (Chatham Islands) Kingsley Baird Abstract Since European discovery of Re¯kohu (Chatham Islands) in 1791, the pacifist Moriori population declined rapidly as a result of introduced diseases (to which they had no immunity) and killing and enslavement by M¯aori iwi (tribes) from the New Zealand ‘mainland’ following their invasion in 1835. When (full-blooded) Tame Horomona Rehe—described on his headstone as the ‘last of the Morioris’— died in 1933, the Moriori were widely considered to be an extinct people. In February 2016, Moriori rangata m¯a tua (elders) and rangatehi (youth), artists and designers, archaeologists, a conservator and an arborist gathered at Ko¯ pinga Marae on Re¯kohu to participate in a w¯a nanga organized by the Hokotehi Moriori Trust. Its purpose was to enlist the combined expertise and commitment of the participants to hokopanopano ka toi Moriori (reignite Moriori arts)—principally those associated with r¯a kau momori (‘carving’ on living ko¯ pi trees)—through discussion, information exchange, speculation, toolmaking and finally, tree carving. In addition to providing a brief cultural and historical background, this paper recounts some of the memory work of the w¯a nanga from the perspective of one of the participants whose fascination for Moriori and the resilience of their culture developed from Michael King’s 1989 book, Moriori: A People Rediscovered.

The census methods were designed to maximise comparability with an earlier census in 1997/98. Based on a complete census of all known Chatham Island shag breeding colonies we estimated the breeding population to be 355 pairs, representing a 58 % decline since 1997/98. We estimated the total Pitt Island shag breeding population to be 434 pairs, a 40% decline since 1997/98 (extrapolated numbers were used for some outlying islands known to hold this species that we did not visit). A series of regular observations showed that breeding activity for both species peaks in October, though there is some notable variation in timing between colonies. Such variation must be taken into consideration in estimating the total breeding population for both species. Both species are distributed across the Chatham Islands group. We found that population declines since 1997/98 have been particularly steep for both species at Pitt Island and outlying islands, with smaller declines on main Chatham Island. A range of anthropogenic threats have been identified, both land-based and at-sea. Because population declines have been particularly pronounced at pest-free, protected out-lying islands we conclude that at-sea factors are likely to be driving the population decline, though more research is required to identify causal factors.

  • SEABIRDS RECORDED at the CHATHAM ISLANDS, 1960 to MAY 1993 by M.J
    SEABIRDS RECORDED AT THE CHATHAM ISLANDS, 1960 TO MAY 1993 By M.J. IMBER Science and Research Directorate, Department of Conservation, P. 0. Box 10420, Wellington ABSTRACT Between 1960 and hlay 1993,62 species of seabirds were recorded at Chatham Islands, including 43 procellariiforms, 5 penguins, 5 pelecaniforms, and 9 hi.Apart &om the 24 breeding species, there were 14 regular visitors, 13 stragglers, 2 rarely seen on migration, and 9 found only beach-cast or as other remains. There is considerable endemism: 8 species or subspecies are confined, or largely confined, to breeding at the Chathams. INTRODUCTION The Chatham Islands (44OS, 176.5OW) are about 900 km east of New Zealand, and 560 km and 720 km respectively north-east of Bounty and Antipodes Islands. The Chatham Islands lie on the Subtropical Convergence (Fleming 1939) - the boundary between subtropical and subantarctic water masses; near the eastern end of the Chatham Rise - a shallow (4'500 m) submarine ridge extending almost to the New Zealand mainland. Chatham Island seabirds can feed over large areas of four marine habitats: the continental shelf of the Chatham Rise; the continental slope around it; and subtropical and subantarctic waters to the north, east, and south. The Chatham Islands' fauna and flora have, however, been very adversely affected by human colonisation for about 500 years (B. McFadgen, pers. cornrn.). Knowledge of the seabird fauna of the Chatham Islands gained up to 1960 is siunmarised in Oliver (1930), Fleming (1939), Dawson (1955, 1973), and papers quoted therein. The present paper summarises published and unpublished data on the seabirds of the archipelago from 1960 to May 1993, from when visits to these islands depended on infrequent passages by ship from Lyttelton, South Island, to the present, when a visit involves a 2-h scheduled flight from Napier, Wellington, or Christchurch, six dayslweek.

EXECUTIVE SUMMARY Annual aerial surveys to count the breeding population of Chatham Island shags were carried out during the 2014, 2015 and 2016 breeding seasons. Each season two aerial surveys of all colonies were undertaken, with an additional early flight in 2016 to count the colonies in Te Whanga Lagoon. The number of Chatham Island shags was estimated at 856 breeding pairs, found in 13 breeding colonies. This result is very similar to that recorded in 1997 (842 pairs) but significantly higher than counts from 2003 and 2011. Methodology was the same in the 1997 and 2014-2016 counts and suggest the Chatham Island shag population has been stable for the last 20 years.

Icebergs were also observed drifting precipitous to the Water’s edge.’ One drifting through Pitt Strait, breaking up around Pitt Island through Pitt Strait was ‘as large in apparent size and one stranded between Pitt and South East (over 900ft in height) as Mangere (an island Islands. The icebergs were carried along by very possibly three-quarters of a mile in size, or more), cold and strong south to south west winds and but not so high.’ He noted that ‘The wind two or arrived following a two-month period in which the three days prior to the arrival of the bergs had winds from the south were bitterly cold. been south and south-south-west, very keen and strong; and on the whole, from September previous, whenever the wind got to the south, it was very cold ...’ When you consider that on average only one tenth of an iceberg is visible above water, the true size of these icebergs was remarkable. The Nautical Magazine for November [1892] cautioned masters of vessels travelling from New Zealand to the United Kingdom that icebergs had been met with in a number of localities south and west of the Cape of Good Hope, in some cases forming ‘impenetrable ice barriers stretching for many miles.’ This very unusual event was widely reported in the newspapers in early 1893.
