Nau mai haere mai - welcome to your New Zealand newsletter.

After sustained attacks on the New Zealand stock exchange and other businesses, the Government Communications Security Bureau (GCSB) issued a warning that more is likely to come. IT expert Dave Parry explains why it has become easier to turn computers into bots, making multi-day attacks more common.

Last week, after three intense days of hearing testimony by victims, Justice Mander met public expectation with his decision to ensure the Christchurch terrorist never again walks free. His sentence of life with no chance of parole is without precedent in New Zealand, and as law expert Alexander Gillespie writes, the only appropriate outcome for an unprecedented crime. Fellow legal expert Kris Gledhill concludes the terrorist’s silence and acceptance of the sentence means an appeal is unlikely.

Meanwhile, as Auckland relaxed COVID-19 restrictions this week amid some concern about the number of new cases, modelling shows the temporary lockdown has improved our chances of eliminating the virus again. Researchers at Te Pūnaha Matatini explain that without it, we would have seen an explosive outbreak.
