All Blacks legend and mental health champion Sir John Kirwan is stepping up to support Kiwis by making a wellbeing app he helped design free during the Covid-19 pandemic.

Mentemia – Italian for "my mind" – was created by Kirwan, who has shared his battle with depression, along with tech entrepreneur Adam Clark and medical advisers.

It provides practical tips and techniques to help users take control of their mental health and wellbeing.

Sir John told Simon and Phil the app was like having a personalised mental health coach in your pocket.
