title: Using Engel curves to estimate CPI bias in a small, open, inflation-targeting economy

authors: Gibson, John

subjects: Consumer Price Index

abstract: The Consumer Price Index (CPI) bias for New Zealand is calculated by estimating the food Engel curves for demographically similar households with the same level of CPI-deflated incomes at different points in time. For the 17 years from 1984 to 2001 the bias in the New Zealand CPI as a cost-of-living index averaged over 1% annually. This bias is similar to estimates for the US when the same method is used over a similar era. Thus, the claim of some statistical agencies that bias in their own CPI is less than the widely discussed bias in the US may not be supported. The estimated CPI bias justifies the initial choice of inflation target for the Reserve Bank of New Zealand but not the recent raising of the target.

title: Advancing tephrochronology as a global dating tool: applications in volcanology, archaeology, and palaeoclimatic research

authors: Lane, C.S.

abstract: Layers of far-travelled volcanic ash (tephra) from explosive volcanic eruptions provide stratigraphic and numerical dating horizons in sedimentary and volcanic sequences. Such tephra layers may be dispersed over tens to thousands of kilometres from source, reaching far beyond individual volcanic regions. Tephrochronology is consequently a truly global dating tool, with applications increasingly widespread across a range of Quaternary and geoscience disciplines. This special issue of the International Focus Group on Tephrochronology and Volcanism (INTAV) showcases some of the many recent advances in tephrochronology, from methodological developments to diverse applications across volcanological, archaeological, and palaeoclimatological research.

title: Tapuwaekiwi tapuaeharuru taiharuru te Whakatōhea toheraoa: Connecting to my iwi and reclamation of identity through endurance running grounded in iwi narratives and tikanga/culture.

authors: Helyar-Magill, Nicholas

abstract: This thesis explores the intersection of endurance, whakapapa, and cultural reconnection through the lens of ultra-marathon running and Te Whakatōhea tīpuna pūrākau. By weaving together personal narratives, historical contexts, and contemporary athletic practices, this research examines the role of endurance sports as a pathway for cultural revitalisation and identity reclamation among Māori athletes.
Endurance is a fundamental characteristic of Te Whakatōhea, embodied not only in the physical feats of long-distance running but also in the iwi's historical resilience through colonisation, raupatu, and cultural disconnection. This research positions ultra-marathon running as both a metaphor and a mechanism for reclaiming whakapapa, fostering well-being, and strengthening the connection between Māori athletes and te ao Māori. Drawing upon Kaupapa Māori methodology, qualitative research methods, and tikanga Māori principles, this research seeks to decolonise endurance sports by embedding iwi narratives, tikanga, and mana whenua engagement into the sport of ultra-running.
A central aim of this research is to develop a culturally grounded framework that integrates Te Whakatōhea pūrākau and tikanga into ultra-marathon events. This framework envisions a race that traverses ancestral pathways, acknowledges the whenua and mana whenua, and fosters a culturally safe environment for Māori athletes. The research questions driving this thesis examine the historical endurance of Te Whakatōhea, the impact of colonisation on Māori participation in endurance sports, and the potential for tikanga to be embedded in ultra-marathon events.
The findings of this research reveal that endurance is deeply woven into the whakapapa of Te Whakatōhea and that ultra-marathon running serves as a powerful means of reconnecting with iwi identity, whenua, and te ao Māori. Through interviews with Māori endurance athletes and an exploration of iwi narratives, this research highlights the transformative potential of culturally embedded endurance sports. Furthermore, the research identifies barriers to Māori participation in ultra-marathons, including historical disenfranchisement from traditional athletic spaces and the predominance of Pākehā worldviews in endurance sports. Addressing these barriers, this thesis proposes a tikanga-based model that seeks to attract greater Māori
participation by integrating kaupapa Māori principles into the design, organisation, and execution of ultra-marathon events.
This research is also a personal journey of endurance and reconnection, reflecting on my own whakapapa as a descendant of Te Whakatōhea and an ultra-marathon runner. Raised outside of the iwi rohe, my path of reclaiming identity through sport mirrors the broader themes of cultural endurance and revitalisation explored in this thesis. By engaging with iwi histories, participating in kaupapa Māori spaces, and embedding tikanga into my athletic practice, I have sought to bridge the gap between past and present, creating a future where Māori endurance athletes can thrive within a culturally affirming space.
Ultimately, this thesis contributes to the growing discourse on Indigenous endurance sports, cultural resilience, and decolonial approaches to athletic participation. It affirms that ultra-marathon running, when grounded in whakapapa and tikanga, has the potential to serve as a tool for cultural reconnection, healing, and identity reclamation for Māori athletes and Te Whakatōhea whānau.
