title: Household bargaining over wealth and the adequacy of women's retirement incomes in New Zealand

authors: Gibson, John

subjects: bargaining

abstract: Bargaining models of household wealth accumulation point to a potential conflict of interest between husbands and wives. Wives are typically younger than their husbands and have longer life expectancy, so they must expect to finance a longer retirement period. Therefore, when they have greater relative bargaining power, households will accumulate more wealth. There is some weak evidence for this in the United States, but this article finds the opposite pattern in New Zealand, where women's greater bargaining power results in a lower net worth in the pre-retirement cohort of couples. In New Zealand, where public pensions are more generous than in the US and are not affected by holdings of private wealth or income, it may not be rational for women with greater relative bargaining power than their spouses to favor wealth accumulation. These results indicate the importance of the policy context when considering household bargaining models.

title: Coastal evolution of the Rangitāiki Plains, Bay of Plenty, Aotearoa-New Zealand

authors: Rackham, Bailey

subjects: Rangitaiki Plains

abstract: The Rangitāiki Plains is a tectonically active alluvial plain in the Eastern Bay of Plenty, New Zealand. Throughout the mid-late Holocene (8 ka to present), the Rangitāiki Plains have undergone substantial geomorphological change, with the coastline prograding approximately 10 km over the past 6.5 ka, leaving relic shoreline features known as beach ridges. Previous studies of the Rangitāiki Plains have utilised tephrochronology and radiocarbon dating to determine the ages of several palaeoshorelines. These dates provided minimum ages for beach ridges and resulted in aging constraints; furthermore, limited textural and geochemical characterisation of beach ridges has hampered understanding of sediment provenance and reworking changes. Addressing these research gaps is important as this knowledge is especially relevant in coastal management, modern climate change, and increasing anthropogenic impacts on the coastline.  

Optically Stimulated Luminescence (OSL) dating on the Rangitāiki Plains produced older beach ridge ages than those derived via tephrochronology. OSL dating also showed that beach ridge ages coincided with volcanic eruption events. The OSL progradation rates extend to much older time frames than those based on tephrochronology, starting at 7.6 ka rather than 5.5 ka. New data concludes a prominent progradation peak up to 43.03 m yr⁻¹ between 5.202±0.368 ka and 5.187±0.447 ka, around the time of the Whakatāne eruption. By 4 ka, progradation had slowed to only 1.14 m yr⁻¹, suggesting that longshore drift occurred earlier than previously calculated (2 ka), or that progradation slowed before longshore drift commenced. XRF and XRD analysis of sediments from Rangitāiki Plains confirms that beach ridge sediments comprise of intermediate igneous sediments that have been tephra fingerprinted to the Taupō Volcanic Zone.

title: Māori language resources and Māori initiatives for teaching and learning te reo Māori

authors: Greensill, Hineitimoana

abstract: As the most southerly member of the Polynesian languages, a sub-group of the widespread Austronesian language family (Harlow, 2007), te reo Māori has been the subject of substantial analysis, documentation, and analyses of its structure since first contact with Captain Cook in 1769 (Whaanga & Greensill, 2014). The history, trials and tribulations of te reo Māori in Aotearoa have been well documented (see, for example, Reedy, 2000; Spolsky, 2005; Waitangi Tribunal, 1986, 2011). The various reasons for the language’s decline has been an area of ongoing debate and critique by academics, researchers, linguists, language activists, parliamentarians and Māori in recent times (see, for example, Bauer, 2008; Benton, 2015; Higgins, Rewi, & Olsen-Reeder, 2014; Rata, 2007; Winitana, 2011).
