Helen Clark has taken on what she's calling "mission impossible".
The former prime minister has agreed to lead a major international review into the coronavirus pandemic.
The World Health Organisation has appointed her to co-chair an independent panel, reviewing how the UN agency and governments around the world responded to the virus.
It will consider how the coronavirus pandemic happened, and how such a thing can be prevented in the future.
Mike Yardley is joined by Tim Wilson and Kerre McIvor to discuss this, along with the other issues making news this week.
