The antithesis of hospitality: Unpacking workplace bullying and advancing a Maori-centric response
(Cambridge University Press in association with Australian and New Zealand Academy of Management, 2026-01-16) Harris C; Haar J; Williamson D; Brougham D
This paper examines workplace bullying in the hospitality sector - an industry paradoxically defined by welcoming others - through a mixed-method approach integrating large-scale quantitative analysis with an in-depth qualitative case study. Study 1 draws on survey data from 2,302 hospitality employees in Aotearoa, New Zealand, to identify the prevalence, patterns, and perpetrators of bullying, and employees' confidence in employer responses. Over half (56%) reported experiencing or witnessing bullying, with women and supervisors most affected. Study 2 explores a Maori hospitality business guided by manaakitanga (care), whanaungatanga (relationships), and tika (fairness), illustrating how Maori values can counter bullying behaviours. Together, the studies reveal the gap between hospitality's ideals and workplace realities, proposing Maori-informed approaches as a pathway towards more respectful, inclusive, and restorative organisational environments. The paper contributes to management and hospitality scholarship by demonstrating how Indigenous relational ethics can operationalise organisational care as an antidote to workplace harm.
Hyperspectral imaging, mineralogy, and degassing: Exploring the volcanic hydrothermal system of Red Crater, Tongariro, Aotearoa New Zealand
(Elsevier BV, 2026-03-01) Sturgess D; Kereszturi G; Mazot A; Sanchez R; Álvarez-Valero AM; Zakharovskyi V
Hydrothermal alteration on volcanoes can compromise the strength and permeability of the host rock, contributing to flank collapses (e.g., Te Maari, 2012) and phreatic eruptions (e.g., Whakaari, 2019). Alteration processes occur at volcanoes hosting hydrothermal systems, where hot, acidic fluid flow is driven by a supply of magmatic heat and gas inputs, resulting in the dissolution of primary minerals and the deposition of secondary assemblages. We investigated hydrothermal alteration at Red Crater, Tongariro, Aotearoa New Zealand, using a combination of laboratory and airborne hyperspectral imaging, mineralogical, and geochemical techniques. Two distinct alteration styles were identified: (1) advanced argillic alteration, characterised by amorphous silica, kaolinite, and alunite, primarily focused at the Red Crater scoria cone, and (2) silicification at Oturere and the Emerald Lakes. The distribution of these units was mapped using supervised image classification of airborne hyperspectral data. Textural and isotopic analyses suggest acid-sulphate alteration is primarily driven by the oxidation of rising H2S in a steam-heated environment. Red Crater hosts four main regions of heightened degassing, coinciding with geothermal surface features and hydrothermal alteration deposits, with 26.2 +- 1.5 t/d of CO2 emissions and an H2S flux of 131.1 g/m2/d. This study presents a conceptual model of hydrothermal alteration processes at Red Crater. Our mapping of alteration and degassing can indicate areas of potential future hazards, and may support simulations assessing flank instability, improving hazard assessment at this active vent.
Canola protein isolate : physicochemical, thermal and rheological characteristics of Canola protein isolate : a thesis submitted in partial fulfilment of requirement for the degree of Master of Food Technology at Massey University, Palmerston North, New Zealand
(Massey University, 2025) Veliyathumaly, Kevin Cyril
This thesis investigates functional and nutritional properties of CanolaPRO, a commercial canola protein isolate. CanolaPRO is made from canola meal, a protein-rich byproduct of canola oil extraction. Canola meal derived products often remain underutilized for human consumption due to its historical anti-nutritional factors and extraction difficulties. Several analyses were conducted to characterize CanolaPRO, including proximate analysis, water holding capacity, foaming capacity, thermal stability (DSC), amino acid profile, particle size distribution and rheology. The results show a high protein purity (89%), low fat and ash and 7% moisture content with water holding capacity measuring at 3.85g water/ g protein. Foaming testing showed initial capacity at 141.7% and stability of 76.8% after 120 minutes, which shows better performance than other plant protein isolates. Thermal analysis shows a denaturation temperature of 89.2°C indicating high stability suitable for food processing. Amino acid profile indicated a balanced and nutritionally rich profile with a high glutamic acid content and other essential amino acids as well as a finer particle size than soy or pea protein isolates. Rheological studies indicate good gel formation with the addition of a moderate amount of hydrocolloid. The overall high purity, and nutritional quality makes CanolaPRO a sustainable alternative plant-based protein isolate.
Targeting the isolation of rumen microbes involved in trimethylamine metabolism using MALDI-TOF MS : a thesis presented in partial fulfilment of the requirements for the degree of Master of Science in Microbiology at Massey University, Manawatū, New Zealand
(Massey University, 2025) Soni, Priya
Trimethylamine (TMA, N(CH3)3) is produced in gut microbial systems, such as the human gut and the rumen, through the microbial degradation of dietary substrates like choline, betaine, and carnitine. The cultivation of microbes involved in TMA metabolism is of mutual interest for both human health and rumen fermentation studies. TMA is a precursor to trimethylamine N-oxide (TMAO), a metabolite correlated with disease, and TMA is also a precursor for methane (CH4) production in ruminants. Microbes that carry genes encoding TMA metabolism have been identified from gut microbial metagenomic sequence data. However, confirming TMA metabolism in individual microbes requires experimental validation using pure cultures. Using genes known to be involved in TMA metabolism, a list of candidate TMA-metabolising strains was identified from bacterial isolates within the Hungate1000 culture collection. The study aimed to isolate new microbes involved in TMA metabolism using the Bruker Biotyper® Matrix-Assisted Laser Desorption/Ionisation Time of-Flight Mass Spectrometry (MALDI-TOF MS) system as a high-throughput screening and identification tool. The MALDI Biotyper® database was expanded by creating mass spectral profiles (MSPs) from rumen-derived candidate strains implicated in TMA metabolism, to assist with the rapid identification of new isolates. Rumen and faecal samples were selectively enriched for microorganisms able to grow on the TMA precursors choline, betaine, and carnitine, and TMA production was confirmed in the choline enrichments. However, purified isolates in this study were unable to produce TMA. Isolated pure cultures were rapidly screened with the MALDI Biotyper® using the expanded targeted database, which resulted in identifications requiring further inclusion of MSPs from the rumen source. MALDI identifications were verified using 16S rRNA gene sequencing of the isolates.
Diet quality and iron status among postpartum women living in Palmerston North, New Zealand : Mother and Infant Nutrition Investigation (MINI) study : a thesis presented in partial fulfilment of the requirements for the degree of Master of Science in Nutrition and Dietetics at Massey University, Auckland, New Zealand
(Massey University, 2025) Davis, Ellen
Background: Iron deficiency (ID) and anaemia are prevalent among postpartum women and represent an important public health concern. During the postpartum period, inadequate iron status can contribute to fatigue, impaired cognitive function and reduced quality of life, with potential consequences for both maternal and infant well-being. Despite the recognised importance of nutrition during this life stage, there is limited research on the relationship between overall diet quality and iron status among postpartum women in New Zealand (NZ). Objective: To investigate the relationship between diet quality and iron status in postpartum women in New Zealand. Methods: This secondary data analysis used the data collected from 87 postpartum women living in Palmerston North, New Zealand. Participants were recruited for the Mother and Infant Nutrition Infant Investigation (MINI) study. At six months postpartum 75 participants completed a weighed four-day food diary (4DDD) to assess dietary intake. Diet quality was calculated using a modified Dietary Guideline Index (DGI) adapted to New Zealand dietary guidelines. Iron status was assessed through serum ferritin (SF) and haemoglobin (Hb) biomarkers. C-reactive protein (CRP) was used to adjust for inflammation. Statistical analysis was conducted to find associations between diet quality, iron status, and sociodemographic factors. Nonparametric data were expressed as median and interquartile range (median [Q1, Q3]), while categorical variables were expressed as frequencies and percentages. Results: The median total dietary guideline index score (TDGIS) for postpartum women was 59.5/100 [54.1, 68.3]. Adherence to individual dietary components varied, with the highest adherence for protein (72% met recommendations) and the lowest for dairy (12%). Only 30.7% of participants met vegetable recommendations, 33.3% for fruit, and 22.7% for grains. The median diet variety score was 26 [23.0, 29.0] out of a possible 65, with participants achieving on average 43.6% of the highest possible variety score. Iron insufficiency (SF<30 μg/L) was confirmed in 12.9% (n=9) of participants. Participants with iron sufficiency had significantly higher total dietary guideline index scores (TDGIS) (60.9 [55.0, 69.1]) compared to iron-insufficient participants (53.6 [46.1, 61.4], p=0.026) out of 100. Grain intake was significantly higher in iron-sufficient participants (4.5 [3.9,5.8]) compared to iron-insufficient participants (3.2 [1.8,4.4], p=0.014). Higher education attainment was positively associated with iron sufficiency and higher total dietary guideline index scores (p<0.001). Conclusion: This is the first study in NZ to investigate the association between diet quality and iron status among the postpartum population in NZ, to the best of our knowledge. The findings of this study suggest that a lower diet quality is associated with an increased risk of insufficient iron levels. This finding reinforces the importance of postpartum nutrition. The positive relationship between diet quality and education highlights the role of community-based nutrition education to support postpartum women, with targeted public health interventions targeted for those at higher risk. Future research should continue to prioritise diet quality while incorporating distinctions between haem and non-haem iron sources and other dietary factors influencing iron absorption to further understand the relationship between diet and iron status in postpartum women.
