Nau mai, haere mai.

The commemoration of old wars is always about more than remembering the “glorious dead”, and the always sad, sometimes noble circumstances of their demise. It inevitably raises questions about the nature of a specific conflict, and about war itself.

Anzac Day in New Zealand has long been imbued with a kind of spiritual dimension beyond its martial origins. Anyone who’s attended a dawn service knows this feeling – sadness for those young lives lost, a fleeting sense of comradeship with those around you that transcends the often transactional nature of the everyday.

But it also requires an intellectual response. There is the notion of our collective coming of age, of course, and the origins of a national identity. Other than that, though, we tend not to dwell on the causes of all that bloodshed – except to mourn the pointlessness of it all from our present vantage.

As Olli Hellmann writes today, “The question of why New Zealand soldiers ended up on Turkish beaches in April 1915 is typically not part of these commemorations. Rather, our collective memories begin with the moment of the early morning landing.”

In fact, the Anzacs were caught up in wider British imperial calculations designed to hasten the collapse of the Ottoman Empire, and which still shape the Middle East today. “Most significantly,” Hellmann writes, “it is the violent conflict over Palestine that can be traced back to colonial power dealings during World War I.”

Anzac Day reminds us, then, that history is not something that can be confined to memorials and cenotaphs. It is a continuum, linking us to events before our time that nonetheless continue to define our world.

From Gallipoli to Gaza: remembering the Anzacs not as a ‘coming of age’ tale but as a lesson for the future

Olli Hellmann, University of Waikato

The roots of today’s Israel-Palestine crisis can be traced back to colonial power dealings during World War I – of which the Gallipoli campaign and Anzac legend are an integral part.

West Antarctica’s ice sheet was smaller thousands of years ago – here’s why this matters today

Dan Lowry, GNS Science; Holly Kyeore Han, NASA

Some 7,000 years ago, West Antarctica’s ice sheet retreated, most likely driven by warmer ocean currents slipping under the ice. This could happen again – unless we cut emissions fast.

Ecosystems are deeply interconnected – environmental research, policy and management should be too

Rebecca Gladstone-Gallagher, University of Auckland, Waipapa Taumata Rau; Conrad Pilditch, University of Waikato; Simon Francis Thrush, University of Auckland, Waipapa Taumata Rau

Pollution on land inevitably ends up in the sea. Policy makers must stop working in silos and instead consider the indirect consequences human impacts on land have for marine environments.

Supermarket facial recognition failure: why automated systems must put the human factor first

Mark Rickerby, University of Canterbury

The Rotorua woman wrongly identified by a supermarket facial recognition system says ethnicity was a ‘huge factor’. Her case shows why human-centered design is needed to avoid misuse, bias and harm.

In demand but disempowered: why low-skilled migrant workers face even worse exploitation under NZ’s new rules

Francis L Collins, University of Auckland, Waipapa Taumata Rau

Other labour migrants in New Zealand enjoy rights broadly in line with those experienced by citizens and permanent residents – ‘low-skilled’ workers should too.

Rugby stadiums are sold as an economic asset – but NZ needs to ask if they’re really worth it

Robert Hamlin, University of Otago

Despite multimillion dollar price tags, rugby stadiums rarely cater to events outside of the sport. So why should communities cover the hefty bill when there is limited benefit to the wider community?

Why the government’s haste in changing the health system could come back to haunt it

Tim Tenbensel, University of Auckland, Waipapa Taumata Rau

The Māori Health Authority is gone, but a law remains that puts primary focus on reducing health inequities – meaning the government may struggle to bridge the gap between rhetoric and policy priority.

NZ education scores must improve – but another polarising ideological pivot isn’t the answer

Bronwyn E Wood, Te Herenga Waka — Victoria University of Wellington; Taylor Hughson, University of Cambridge

Key education policy decisions in the early 2000s have not produced the desired results. But broad bipartisan agreement is now needed to give children and teachers the greatest chance of success.

The government is basing its school truancy response on data – but by-the-numbers solutions aren’t enough

Claire Breen, University of Waikato

Punishing parents of truant children misses factors – such as poverty and hunger – keeping some children out of school.

Light pollution affects coastal ecosystems too – this underwater ‘canary’ is warning of the impacts

Kathleen Laura Sterup, Te Herenga Waka — Victoria University of Wellington; Abigail M Smith, University of Otago

The common triplefin is helping marine scientists understand the negative effects of ‘skyglow’ on coastal fish, which are already more exposed to microplastics, chemicals and noise pollution.
