Nau mai, haere mai.

Living in congested, infrastructurally challenged Auckland can often feel like being in a permanent twilight zone. We keep hearing about the transport improvements that are coming, but the orange cones and traffic jams feel awfully permanent.

And according to Timothy Welch’s review of the new National Land Transport Programme, relief is not around the next (poorly signposted) corner. The bulk of transport funding for the next three years is going on roads and their upkeep, with little left for cycleways or other alternatives to the internal combustion engine.

But as Welsh also makes clear, even the billions being spent on so-called Roads of National Significance won’t see anything new actually built in that timeframe. “The roads are several years, if not decades, away from becoming a reality,” he writes. “Instead, these funds will be dedicated to extensive planning, design and preparatory work, rather than actual construction.”

Overall, Welch argues, the programme “isn’t just a missed opportunity, it’s a deliberate U-turn away from the sustainable, efficient urban transport systems the cities need.”

Also today, parents of teenagers will no doubt be interested in new research about the impact of evening screen time on sleep patterns. The traditional advice is to cut it down to improve sleep. But Rachael Taylor’s new research shows that screen time before bed might not be the problem – rather, it is screen time while actually in bed that could be an issue.

It’s almost impossible to keep teens off their phones in bed – but new research shows it really does affect their sleep

Rachael Taylor, University of Otago

Parents are regularly told to limit their children’s screen time during the evening. But new research suggests it is using digital devices while in bed that is the bigger problem.

‘The pāua that clings to the sea’: a new species of abalone found only in waters off a remote NZ island chain

Kerry Walton, Museum of New Zealand Te Papa Tongarewa; Hamish G Spencer, University of Otago; Nic Rawlence, University of Otago

The discovery of the Manawatāwhi pāua, unique to the Three Kings Islands, highlights the need to build taxonomic expertise to speed up work to describe thousands of as-yet unnamed species.

‘Room for everyone’: how Kīngi Tūheitia’s message of unity offered an alternative to divisive Treaty politics

Dominic O'Sullivan, Charles Sturt University

With the death of Kīngi Tūheitia at a time of heightened tensions around Māori-Crown relations, the Kingitanga movement’s founding principle of kotahitanga – unity – remains as relevant as ever.

Without sanctions, making companies disclose their environmental and social impacts has limited effect

Charl de Villiers, University of Auckland, Waipapa Taumata Rau

Consumers and investors are expecting more from businesses when it comes to the environment. But new research shows transparency does not always mean companies improve their performance.

NZ’s Space Agency is both regulator and developer of the aerospace industry – that’s a point of tension

Priyanka Dhopade, University of Auckland, Waipapa Taumata Rau; Catherine Qualtrough, University of Auckland, Waipapa Taumata Rau

The New Zealand Space Agency’s dual role as regulator and sector developer introduces a conflict of interest and skews the aerospace industry towards economic growth, at the cost of sustainability.

What if Big Oil championed – and profited from – the green transition? Here’s how it could work

Richard Meade, Griffith University

Repurposing fossil fuel infrastructures to supply clean fuels might make more immediate economic and environmental sense than mass electrification of transport and industry.

Labour or leisure? Why a universal basic income might foster wellbeing but not productivity

Alexander Plum, Auckland University of Technology; Kabir Dasgupta, Auckland University of Technology

As AI and automation transform the workplace, a universal basic income is one possible solution. But research is beginning to show the unpredictable outcomes of such unconditional cash transfers.

Ocean heat is changing marine food webs – with far-reaching consequences for NZ fisheries and sea life

Anne Rolton Vignier, Cawthron Institute; Kirsty Smith, Cawthron Institute

As the ocean warms, toxic algal blooms are on the rise in the waters off New Zealand, causing the highest number of shellfish harvest closures in a decade.

Having it all is a myth: family and personal commitments are pushing women out of their own businesses

Janine Swail, University of Auckland, Waipapa Taumata Rau; Susan Marlow, University of Nottingham

Starting a business or being self-employed is touted as a way for women to attain better work-life balance. But new research suggests this is not always a realistic goal.

DEI policies work best when they are designed to include everyone and are backed by evidence

Henry Tran, University of South Carolina

Diversity programs that emphasize quick, symbolic wins are a lot less useful than building a shared understanding of fairness.
