title: Proxy evidence of relative sea level change indicators and implications  Raglan (Whaingaroa) harbour  New Zealand

authors: Carter, Michael. J.

subjects: Raglan Harbour

abstract: Geological observations and macrofossil dating of 4 raised marine terraces reveal active tectonic displacement in the Raglan Harbour, New Zealand (NZ). The 120 km-long harbour shoreline displays multiple examples of block-faulting, stratigraphic displacement, and fresh stress release fracture zones within rock sea-cliffs. Tide-zone rock platforms are indicative of a long-term uplift trend within a major portion of the harbour.  Vertical land movement (VLM) rates are found to vary at different locations, signifying active fault displacement. Six proxies establish VLM magnitude and timing constraints applicable to the last 7 decades. One further proxy establishes maximum relative sea level (RSL) throughout the last 23.5 Ka at a specific location in the harbour.
Seventeen 14C dated macrofossils from 4 raised marine terraces identified 2 groups of ages: pMC ~ 1 to 6.5 Ca yr BP and   ̴ 6.5 Ka yr BP respectively.  Tide dissolution notches in rocks identifiable in historical photographs are compared with modern equivalents at 2 locations. These depict no apparent change in the upper dissolution notch boundary elevations since 1910.  Characterisation and U-Th dating of a speleothem located   ̴ 0.4 m above the modern high tide level signifies that RSL is near its   ̴ 23.5 Ka maximum at this location. Historic aerial imagery identifies a marine terrace that uplifted by < 0.4 m within the period 1979 to 1997. A fault demarcates this feature from a second terrace with stratigraphic evidence of a markedly different VLM history, indicating that the fault is active. Raised trace fossil castings exposed in the foreshore’s mid-tide zone further substantiates evidence of relatively recent uplift at this location.

title: The last post? Post-postmodernism and the linguistic u-turn

authors: Peters, Michael A.

subjects: Linguistic turn

abstract: This paper adopts an autobiographical tone to review the linguistic turn and its demise at the hands Richard Rorty. Rorty, along with Continental philosophers like Lyotard rescued us from a philosophical delusion that we might achieve a neutral analysis resulting in linguistic and conceptual hygiene. This view became the basis of a highly influential doctrine in philosophy of education during the 1970s under R. S. Peters and the London school. I review the Wittgensteininspired movement and its conceptual affinities with postpositivism, postmodernism and postcoloniality as the dominating motifs of the age we have now passed beyond. © Michael A.

title: Whakapapa Ora: An exploration of Māori Identity through Whakapapa

authors: Ngawhare, Rauna Maria

subjects: Whakapapa

abstract: This thesis set out to explore Māori identity through access to whakapapa. As whānau, hapū, and iwi, we have a responsibility to future generations to ensure access to whakapapa is inclusive. Therefore, access to whakapapa in today’s world must also consider contemporary approaches, including the use of technology to engage the next generation in learning about, and connecting with, whakapapa. 

The research is centred on the question ‘How can whakapapa be accessed safely in culturally appropriate ways that evolve with twenty-first-century systems?’ I use contemporary pūrākau to review traditional access to whakapapa, supported by a Kaupapa Māori approach to frame the research. Kaupapa Māori Theory, Ngā Takepū, and Pūrākau Methodology (underpinned by Qualitative Methodology and Thematic Analysis) give an overview of the methodologies and methods used herein. Five semi-structured interviews with whānau affiliated to Ngāti Kahungunu ki Heretaunga and Taranaki iwi were conducted. Each share their lived experiences as Māori to support an understanding of identity through whakapapa.  

The results suggest whānau Māori who access whakapapa (in its many forms), will undergo a process of decolonisation. This requires adequate support in the form of kaitiakitanga, necessary to gain a better understanding of Te Ao Māori tikanga and kawa. Whakapapa access develops this process. However, further research is required to fully appreciate ‘Whakapapa Ora’ as a foundation for safe access to whakapapa in the twenty-first century.
