The last Omicron wave affected younger people. But the new BA.5 variant is seeing case numbers in older age groups higher than ever before – just as hospitals are under the most pressure.
Invasive mammals have already removed some native bird species from our cities. It’s why urban forest restoration and predator control are crucial to support the ‘ghosts of predation past’.
New Zealand’s system of managed quarantine at the border may soon be less important, but we could well need to stand it up again quickly if a new COVID-19 variant emerges.
Several superspreading events had likely infected more than 200 people before New Zealand’s Delta outbreak was detected and the country went into a strict lockdown last week.
Indigenous marine governance is experiencing a revival throughout Oceania, building on traditional worldviews that acknowledge connections between people and all parts of ocean ecosystems.
Given long-term forecasts for growing urban populations and an increasingly variable climate, local authorities will have to think about how best to encourage people to conserve water.
Border restrictions and quarantine have kept COVID-19 out of New Zealand, but new modelling shows contact tracing and quick isolation would control an outbreak, without the need for another lockdown.

As the trade spat between China and the US continues, it is likely to spill over to other countries. For Australia and New Zealand, this could bring both risks and opportunities.
Tracing extinctions that happened centuries ago is difficult. But in New Zealand, the last place to be settled some 750 years ago, ancestral Māori oral traditions retain clues about lost species.
