title: Māori, census 2018 and data sovereignty

authors: Kukutai, Tahu

abstract: This webinar explores the issues with the 2018 Census data collection and examines what the implications could be for communities and funding.  See below to read some relevant articles prior to the webinar.

Our presenters also discuss iwi data sovereignty and data bias and the reasons why we should all pay more attention to the quality of the data we provide, use and collect.

title: A newly-available resource for historians of early New Zealand: The Marist Missionary Letters (1838-54)

authors: Jennings, William

abstract: The 7000 pages of primary documents of the Lettres reçues d’Océanie constitute a vast new source for the study of the Pacific during the period 1838-54. Published in 2009 after sixteen years of transcription, the Lettres are the collected correspondence of the first French Marist missionaries to New Zealand and other Pacific islands. In the words of Pacific historian Hugh Laracy, they are ‘the single most important foundational contribution to Pacific history in its fullest extent since J. C. Beaglehole’s magisterial editions of James Cook’s Journals. About 2000 of those pages are transcripts of letters written in New Zealand that open up a fresh perspective of life before the wars of the 1860’s. This paper will locate the early French Marist Māori mission within the context of New Zealand public history before exploring how the Lettres reçues d’Océanie can complement existing views of early colonial New Zealand. To better contextualise the correspondence, it would be useful to begin with a brief background of the Marists’ presence in New Zealand.

title: Development of a novel cyanide-free method for analysis of vitamin B₁₂ in milk-based infant formula

authors: Li, Yanan

abstract: The analysis of vitamin B₁₂ in infant formulas requires the use of cyanide during the sample preparation process to convert the three unstable vitamers (hydroxocobalamin, methylcobalamin and adenosylcobalamin) to cyanocobalamin, the most stable form of vitamin B₁₂. The undesirable handling of cyanide for the analyst in the laboratory and the associated safety risk indicates a clear necessity for development of a cyanide-free method for vitamin B₁₂ analysis without compromising the analytical quality.
This doctoral research demonstrates the possibility of using cobalamin-derived α-ribazole to represent total vitamin B₁₂, since the α-ribazole exists in all vitamin B₁₂ forms removing the necessity for conversion. The absence of a commercial standard of α-ribazole required its in-house isolation from a cyanocobalamin standard. The α-ribazole was released through consecutive acidic hydrolysis and dephosphorylation by alkaline phosphatase. The freed α-ribazole was collected by boronate affinity chromatography and concentrated by lyophilisation. α-Ribazole was identified and characterised by nuclear magnetic resonance spectroscopy and liquid chromatography mass spectrometry to demonstrate its suitability as a standard. This protocol was optimised and adopted in the sample preparation for analysing vitamin B₁₂ in infant formulas. Several extra steps were added to eliminate or limit interferences, including protein denaturation and sugar removal using C₁₈ solid phase extraction. The final analyte was quantified using hydrophilic interaction liquid chromatography with fluorescence detection.
The single laboratory validation experiment showed that this cyanide-free method is fit for purpose. Analysis of various milk-based infant formulas and comparison with current procedure demonstrated no bias for vitamin B₁₂ analysis.
