title: An integrated sequence stratigraphic, palaeoenvironmental, and chronostratigraphic analysis of the Tangahoe Formation, southern Taranaki coast, with implications for mid-Pliocene (c. 3.4–3.0 Ma) glacio-eustatic sea-level changes

authors: Naish, Timothy R.

subjects: Tangahoe Formation

abstract: Sediments of the mid-Pliocene (c. 3.4–3.0 Ma) Tangahoe Formation exposed in cliffs along the South Taranaki coastline of New Zealand comprise a 270 m thick, cyclothemic shallow-marine succession that has been gently warped into a north to south trending, low angle anticline. This study examines the sedimentologic, faunal, and petrographic characteristics of 10 Milankovitch-scale (6th order), shallow-marine depositional sequences exposed on the western limb of the anticline. The sequences are recognised on the basis of the cyclic vertical stacking of their constituent lithofacies, which are bound by sharp wave cut surfaces produced during transgressive shoreface erosion. Each sequence comprises three parts: (1) a 0.2–2 m thick, deepening upwards, basal suite of reworked bioclastic lag deposits (onlap shellbed) and/or an overlying matrix supported, molluscan shellbed of offshore shelf affinity (backlap shellbed); (2) a 5–20 m thick, gradually shoaling, aggradational siltstone succession; and (3) a 5–10 m thick, strongly progradational, well sorted “forced regressive” shoreline sandstone. The three-fold subdivision corresponds to transgressive, highstand, and regressive systems tracts (TSTs, HSTs, and RSTs) respectively, and represents deposition during a glacio-eustatic sea-level cycle. Lowstand systems tract sediments are not recorded because the outcrop is situated c. 100 km east of the contemporary shelf edge and was subaerially exposed at that time. Well developed, sharp- and gradational-based forced regressive sandstones contain a variety of storm-emplaced sedimentary structures, and represent the rapid and abrupt basinward translation of the shoreline on to a storm dominated, shallow shelf during eustatic sea-level fall. Increased supply of sediment from north-west South Island during “forced regression” is indicated from petrographic analyses of the heavy mineralogy of the sandstones. A chronology based on biostratigraphy and the correlation of a new magnetostratigraphy to the magnetic polarity timescale allows: (1) identification of the Mammoth (C2An.2r) and Kaena (C2An.1r) subchrons; (2) correlation of the coastal section to the Waipipian Stage; and (3) estimation of the age of the coastal section as 3.36–3.06 Ma. Qualitative assessment of foraminiferal census data and molluscan palaeoecology reveals cyclic changes in water depth from shelf to shoreline environments during the deposition of each sequence. Seven major cycles in water depth of between 20 and 50m have been correlated to individual 40 ka glacio-eustatic sea-level cycles on the marine oxygen isotope timescale. The coastal Tangahoe Formation provides a shallow-marine record of global glacio-eustasy prior to the development of significant ice sheets on Northern Hemisphere continents, and supports evidence from marine δ18O archives that changes in Antarctic ice volume were occurring during the Pliocene.

title: Literature review: Transition from early childhood education to school

authors: Peters, Sally

subjects: New Zealand

abstract: The review’s purpose was to deepen understanding of transition to school by critically analysing research literature. The focus was on what successful transitions to school look like, the factors that play a role in how well children transition from ECE to school, and the ways in which children can be supported by teachers and families to transition as successfully as possible.

authors: Nock, Sophie

subjects: Tikanga Māori

abstract: Ko te wherawhera a tēnei tuhinga he titiro ki ngā io mai i ngā tikanga o te ao Māori, ā, ki ngā hau kino e whakataurekareka ana i ā tātou tikanga Māori. Kei roto i ngā iwi katoa o te ao ā rātau tikanga, engari, ko ngā whakamāramatanga o aua tikanga kei te mau ruhiruhi noa i roto i ngā hinengaro o ngā tāngata o tēnā iwi, tēnā iwi, ā, kua ngaro katoa atu rānei. Nā reira, ko tāku he rapu i aua māramatanga kei muri i ngā tikanga Māori, ā, he rapu anō hoki i ngā tāmitanga, i ngā pēhitanga a tauiwi mā, ko te mutunga ka whakapōrearea i ā tātou tikanga Māori.
Ko te aronga rangahau mō tēnei kaupapa he whai i ngā tuhinga me ngā kōrero i ahu mai i te ao Māori me te ao Pākehā. Ko ngā rauemi nei i ahu mai i ngā kohikohinga kōrero tawhito me ngā tuhinga a te hunga o roto i ngā tau kātahi anō ka pahure ake. Ko ngā kōrero tawhito nei hei whakaata ake i te huringa o te ao, ā, ka tīkina atu aua kōrero hei ārahi i te hunga ora kia mau tonu ai ā tātou tikanga Māori.
Ki te whai haere i tēnei momo kaupapa, me mātua whai rawa i ngā kōrero ā-waha hei whakaatu mai, ina kāore hoki i āta tuhia whānuihia ngā kōrero i maringi mai i te hinengaro o te hunga whakautu pātai. Ko ngā kohinga kōrero ā-waha hei tohu i ngā tikanga me ngā whakapono ake i pā mai ki a rātou i te wā e tipu ake ana.
Ko ētahi o ngā kaikōrero i tipu ake i roto i te tūturutanga o te ao Māori, arā, i tipu ake i ngā rekereke o ō rātou kuia, koroua, ā, ko ētahi ahakoa he Māori, i tipu ake anō i roto i te reo me ētahi o ngā tikanga Māori, ko ētahi anō i noho hoki i te tāone.
Ko ngā kaupapa ka whakaarahia ake e tēnei rangahau ko ngā tikanga e hāngai pū ana, e whakamahia ana, e kitea ana, e whakaatu ana anō hoki i ngā whakapono o te Māori. Kāti, ka tirohia ētahi tikanga i waenga i te whānau, ētahi atu tikanga hāngai pū ana ki te manaaki tangata i runga marae me te whakaaro ake ki ngā tohu e tika ana ki te whakanui manuhiri.
He roa te Māori e noho ana i te ao Pākehā, mai i tō rātou taenga mai i te rau tau tekau mā waru. Ko te nuinga o tātau kua roa kē te wehenga mai i te ao tūturu ake o te Māori. Ko ētahi tāngata e pupuri tonu ana i ētahi o ā tātou tikanga, ko ētahi kāhore noa e mōhio ana. Tēnā pea, ko ngā whakatūpato i mau, engari, ko ngā whakamārama kei te ngaro. Kāti, ko te tūmanako mō tēnei tuhingaroa ko te whakahoutia anō o te here ki ā tātou tikanga. Ka āhei hoki te hunga e ngākaunui ana ki te kaupapa nei ki te whai whakaaro, te whai māramatanga.
Ko tēnei tuhinga he tauira hei whakaatu atu he mahi pakeke te hopu, te tiaki, te manaaki me te ako hoki i ngā mātauranga o tuawhakarere. He pēnei anō ēnei tikanga mō nāianei, he toimaha tonu te kawe, te whakaū.
Heoi, ka whakatakia mai ngā kōrero i te orokohanga o te ao hei raranga ake hei whāriki mō te tikanga Māori. Tuatahi, ka tirohia ētahi o ngā whenu o tēnei mahi whata, arā, te ahunga mai o te tikanga Māori me ngā tikanga huhua i whakatauiratia mai e ngā atua Māori. Whai muri atu kei te upoko tuarua, ka whakaraupapahia mai ngā kōrero a te hunga whakautu pātai kia āta kitea ai ō rātou whakaaro mō te tikanga Māori. Ka hāngai pū tonu tēnei titiro ki ngā momo pātai, ā, ka tirohia hoki ngā whakahokinga a taua hunga nā.
Kei te upoko tuatoru ka huri te titiro ki ngā hau pūkeri e tūkino nei i ā tātou tikanga Māori. Tuatahi, ka horahia ngā kōrero, ngā tikanga mō te āhua o te noho a te Māori o mua, kia āta kitea ai i pēhea te āhua o tōna whakahaere i tōna ao o mua. Kātahi, ka āta tirohia ētahi ture Pākehā e tīhaehae nei i ā tātou tikanga, pēnei i te ngaro haere o te reo Māori, te haehae haere o ā tātou tikanga Māori. Ka mutu, ka huri ake ki te whai whakaaro ki ētahi o ngā raru i pā mai ki te tikanga Māori i te neketanga o te Māori ki te tāone noho ai, mahi ai.
Kei te upoko tuawhā ētahi tauira mō ngā tūmomo tikanga e mahia ana e te Māori i waenganui i tōna whānau. Ka tirohia te ringa tapu o te tikanga hei whakaohooho ake i te hinengaro, hei whakatakoto māramatanga mō aua tikanga hoki.
Kei te upoko tuarima te tirohanga ki ngā momo tikanga i runga marae, me ngā momo tohu Māori e whakaatu mai ana i te rangatiratanga o te iwi, pēnei i ngā tohu kino, i ngā tohu ora rānei. Ka tirohia ētahi whakamāramatanga mō te āhua o te noho piri o te Māori ki tōna taiao, he aha ngā kōrero a te taiao ki te Māori, he aha hoki ngā kōrero a ngā kararehe o te taiao.
Hei whakakapi ake i te tuhinga nei ko te whakarāpopototanga. I konei ka titiro whakamuri ki ngā āhuatanga kua ara ake. Ka whakaraupapahia ngā whakakitenga me ngā whakaputanga hei whakaohooho, hei whakaarotanga ake mō te ao kei mua e pā ana ki ā tātou tikanga Māori.
