Nau mai, haere mai.

New prime minister Christopher Luxon has spent much of his time since taking office defending various coalition agreements from expert criticism. Tobacco, Treaty of Waitangi and tax policies have all been under intense scrutiny – as has the decision to lodge a “reservation” against amendments to World Health Organization (WHO) regulations.

Labour leader Chris Hipkins said the government was “dancing dangerously close to endorsing conspiracy theories”, while his health spokesperson expressed concern that online “rubbish” had made its way into the coalition agreement.

At issue are proposed changes and additions to the WHO’s international health regulations – essentially, the rules setting out the rights and obligations of member countries when it comes to the health of their populations.

As part of its coalition agreement with National, NZ First has required a “national interest test” to be applied to UN agreements, and an assurance “domestic law holds primacy over any international agreements”.

But these kinds of checks and balances are already well established in New Zealand law and parliamentary convention. As Claire Breen and Alexander Gillespie outline today, any international agreement or treaty goes through a rigorous legislative process before ratification and adoption into domestic law – including a national interest analysis.

“The entire process affirms New Zealand’s sovereignty,” they write. While this may never be enough for some, it should at least reassure a majority that New Zealand is well served by its own democratic institutions.

Also, while you're here, we are 50% toward our goal of signing up 600 new regular supporters this December. Thanks so much to everyone who has contributed. If you can afford it, there is still time to help us hit our goal. Until next week, mā te wā.

NZ First fears over WHO regulations are misplaced – robust checks and balances already exist

Claire Breen, University of Waikato; Alexander Gillespie, University of Waikato

Despite demands for an urgent ‘reservation’ and ‘national interest test’ over new WHO regulations, New Zealand’s sovereignty is not at risk from international agreements or treaties.

Humans, rats and dogs pushed the takahē into Fiordland – new genetic research maps its dramatic journey

Examining the DNA of the takahē has upended long-held beliefs about how the flightless bird ended up on the southwestern tip of New Zealand. This new knowledge can help future conservation efforts.

COP28: with a ‘loss and damage’ fund in place, protecting climate refugees is more urgent than ever

Dr. Dalila Gharbaoui, University of Canterbury

A recently signed Australia-Tuvalu citizenship agreement offers people displaced by climate change a chance to ‘move with dignity’. But staying with dignity has to be an option too.

Nicola Willis warns of fiscal ‘snakes and snails’ – her first mini-budget will be a test of NZ’s no-surprises finance rules

Michael Ryan, University of Waikato

The Public Finance Act is designed to prevent shocks and ‘fiscal cliffs’. And it is unlikely any problems faced by Nicola Willis will match the scale of those that dogged previous governments.

COP28: the climate summit’s first Health Day points to what needs to change in NZ

Alistair Woodward, University of Auckland

Nations struggle if the health of their population fails. But good health is seriously threatened by climate change. So putting health at the centre of climate action makes sense.

The news is fading from sight on big social media platforms – where does that leave journalism?

Merja Myllylahti, Auckland University of Technology

Social media platforms are abandoning news – which is bad news for traditional media organisations that have come to rely on them for consumers.

Is Winston Peters right to call state-funded journalism ‘bribery’ – or is there a bigger threat to democracy?

Peter Thompson, Te Herenga Waka — Victoria University of Wellington

The Public Interest Journalism Fund became a lightning rod for disinformation well before Winston Peters likened it to ‘bribery’. Policy making has already been compromised as a result.
