Nau mai haere mai – welcome to this week’s newsletter.

It’s hard keeping up with politics these days, right? In fact, there are people joking on social media that they’re old enough to remember when Todd Muller was leader of the National Party.

Another week, another leader: in this edition, Massey University political scientist Grant Duncan examines National’s desperate gamble that Judith Collins can counter what has been called the “Jacinda effect”. Although, even as I write, she is having to quell the flames of another scandal, this time involving now-resigned MP Andrew Falloon.

Will this election calm down or are these merely the early signs of crazier times to come? Either way, I hope you will follow our political coverage as the next two months unfold. We are assembling a fantastic team of expert commentators, and we’ll be going beyond the day-to-day skirmishing to analyse the issues and policy debates that really matter.

And don’t worry, we are mindful that life exists outside of politics. This week you can also find fantastic stories about the question of paying for quarantine, how we can stop the coronavirus at our borders for the foreseeable future, the development of an early-warning system for our volcanic areas and new forecasting tools to predict tropical cyclones much earlier, and how parents might broach those difficult conversations with kids.

Don’t forget to check out all the other stories on our New Zealand homepage. Happy reading and thank you for supporting The Conversation.
