INTRODUCTION 1 Harataonga, Aotea/Great Barrier Island (Craig Potton) ENDNOTES 1 Cambridge English Dictionary 2 PROTECTING THE HAURAKI GULF ISLANDS PART ONE: OVERALL CONTEXT 2. THE HAURAKI GULF “The Hauraki Gulf has a quality and diversity of biology and landscape that makes it outstanding within New Zealand. The islands of the Gulf are valued as habitats of plants and animals, once common, now rare, and are often the only places where these species exist naturally.” 1 The Hauraki Gulf/Tīkapa Moana/Te Moananui-o-Toi is a place of outstanding landscapes, rich indigenous biodiversity and spiritual importance to Māori. It is an area used by many to live and work, for recreation and for the sustenance of human health, wellbeing and spirit. The Gulf covers 1.2 million ha of ocean stretching from Pākiri in the north-west, around the seaward side of the Mokohinau Islands and Aotea/Great Barrier Island and down to the south of Whangamatā on the eastern side of the Coromandel Peninsula (see Figure 2.1). The inner Gulf is sheltered to the east by Great Barrier Island, and to the west and south, by the mainland. This means it is exposed only to the northern winds prompting its name: ‘the northern wind’ – hau (wind) and raki (north). Within the Gulf there are more than 65 islands, many of which are protected and managed by the Department of Conservation (DOC) as public conservation land. Of the islands in the Hauraki Gulf that are larger than 10ha, 43 per cent are predator free including Rākino Island (but not Waiheke or Aotea/Great Barrier islands), making it an area Figure 2.4: Map of the Hauraki Gulf Marine Park and catchments 2 Figure 2.1 Hauraki Gulf Marine Park and catchments particularly rich in native bird and other life. 2: LESSONS LEARNED FROM SEA CHANGE TAI TIMU TAI PARI 15 2.1 Geological formation of islands Stony Batter, Waiheke Island The Hauraki Gulf was formed following the last ice age, over 20,000 years ago, when the sea levels were 130m lower than present levels.3 At that time, the seabed of the Gulf would likely have been low lying plains dominated by the volcanic cones of Aotea/Great Barrier and Te Hauturu-o-Toi/Little Barrier.4 The other islands of the Gulf would have been the hills and ridges punctuating the plains.
