Wine is a complicated product with many features and attributes. A simple stroll down the supermarket aisle reveals hundreds of wines on display – from strange bottle shapes to wine varieties that cannot be pronounced. Wine has been integral to many cultures and, for centuries, has accompanied the rise and fall of empires. In this presentation, Dr Barry Wong will discuss modern consumer attitudes and behaviour towards wine. How do we react to certain wines? Or why are we drawn to one particular wine and not the other? As part of the presentation, he will share some emerging trends in the research conducted by his masters students in Hawke’s Bay covering organic wine, no- and low-alcohol (NoLo) wine, and alternative wine packaging.

Dr Barry Wong has been a Postgraduate Lecturer in Wine Business at the Eastern Institute of Technology (EIT) since 2023. Before moving to Hawke’s Bay, he completed a PhD in Sensory and Consumer Science at Auckland University of Technology.

His doctoral research explored New Zealand consumers’ sensory and flavour perception of Korean rice wine. Currently, his research focuses on consumer attitudes and behaviour towards food and beverages using a range of research methods.

Kauri trees are one of the largest and magnificent living beings on the planet, dominating the northern forests of Aotearoa-New Zealand. But our iconic kauri were plundered for their timber during the 19^th and 20^th centuries and are now further threatened by a micro-organism spreading through the forest, killing trees and destroying whole ecosystems. What causes kauri dieback, where did it come from, how does it attack kauri, how does it spread, and most importantly, what can be done about it?

For the past 42 years, Dr Ian Horner has worked as a Plant Pathologist for New Zealand Science Institutes from DSIR to The Bioeconomy Science Institute. His work has focussed on the biology and control of various diseases that have threatened New Zealand’s horticultural industries and forests. For the past 20 years he has studied our kauri forests and the biology and potential control of kauri dieback disease. Ian will present a summary of what we have learned about kauri and the disease threatening its very existence, and provide an optimistic but challenging view of what can be done to manage it and preserve our iconic kauri forests for future generations.

Agriculture sits at the centre of one of the defining challenges of our time: producing nutritious food while responding to climate change. As pressure grows to reduce greenhouse gas emissions from livestock systems, new technologies are rapidly emerging that could reshape the future of farming in New Zealand and beyond.

In this upcoming lecture, Dr Sinead Leahy, Principal Scientist at the Ag Emissions Centre, will explore the science behind low-emissions farming and the technologies being developed to reduce methane and nitrous oxide emissions from ruminant livestock systems. Drawing on both international and New Zealand research programmes, the talk will examine approaches including vaccines, inhibitors, selective breeding, and microbial technologies, as well as the opportunities and challenges of applying these solutions in pasture-based farming systems.

Dr Leahy is widely recognised for her leadership in agricultural greenhouse gas mitigation research. She has over 20 years of experience in agricultural science and climate change, and currently serves in several major international science leadership roles, including as Co-Chair of the Livestock Research Group of the Global Research Alliance on Agricultural Greenhouse Gases and as a lead author for the upcoming IPCC AR7 Assessment Report.

This promises to be a timely and thought-provoking evening exploring how science and innovation may help shape more sustainable and productive farming systems for the future.

This year’s Geoscience Tour lecture will review 25 years of trenching active faults in volcanic environments and how a scientist’s perspective on tectonics close to volcanoes changed through that time, from the simple utilisation of volcanic stratigraphy as timelines for paleo- earthquake history to a realisation that volcanic and tectonic processes are so intimately connected that one cannot be understood without the other. Pilar will show paleoseismic evidence based on criteria that she developed to distinguish types of earthquakes–eruption associations. Paleoseismic data, combined with geomorphology, borehole data, and geophysics, revealed strong temporal links between fault ruptures and volcanic eruptions. She will also draw on worldwide historical examples and stress modelling to infer possible crustal processes that can explain these time associations. Collectively, these studies improve our understanding of how volcanic eruptions and unrest are linked to active faults and earthquakes in the TVZ.

Pilar is an internationally respected earthquake geologist and principal scientist whose research on active faults and volcano–tectonic interactions in Aotearoa New Zealand has had a transformative impact on our understanding of natural hazards. Pilar’s recent studies show that the recurrence of fault ruptures in the Taupō Volcanic Zone (TVZ) can be strongly modulated by volcanic activity, and vice versa. The novelty of her work lies in combining paleoseismic trenching with multidisciplinary approaches to demonstrate causal links between earthquakes and eruptions. This
represents a paradigm shift for New Zealand hazard science.

As we commemorate the 1931 Hawke’s Bay earthquake, this talk turns our attention to another major — and much less well-known — event in our region’s past. The February 23rd, 1863 Waipukurau Earthquake was described by some who experienced both events as being just as violent and damaging as 1931.

Felt across much of Aotearoa New Zealand, the 1863 earthquake caused widespread damage in Napier and central Hawke’s Bay, and may have been as large as magnitude 7.5. Despite this, it remains poorly documented. This lecture presents new research reconstructing its felt intensity across New Zealand, examining impacts on buildings and the natural landscape — including the diversion of the Waipawa River — and recent efforts to identify the source faults east of Waipukurau–Pukehou.

Rob Langridge is an Earthquake Geologist with Earth Sciences NZ, specialising in active faulting, surface rupture, and the earthquake history of Aotearoa New Zealand. His work focuses on understanding past large earthquakes to better inform present-day seismic risk.
