The Prime Minister has taken part in a panel discussion on Mental Health on Thursday morning (NZ time) alongside Prince William at the World Economic Forum in Davos. It's estimated that one in four people will experience mental illness in their lives costing the global economy an estimated $6 trillion by 2030. Jacinda Ardern was asked why she had made mental health a priority issue for her government. Prince William said that there are many people who are still suffering in silence due to the stigma of having a mental illness, but there is a generational shift occurring. Ms Ardern said people in New Zealand do talk about mental health but that doesn't mean there isn't a stigma. She thanked Sir John Kirwan for his work on mental health issues, as well as Prince William.
