Sophie Devine says her mental health was a factor in her decision to relinquish the White Ferns' Twenty20 captaincy

The 34-year-old all-rounder will step down from the role after October's World Cup in the UAE, but will continue to skipper the one-day side.

Devine says she won't be playing forever, and wants to focus on playing and nurturing the next generation - which goes hand in hand with her mental health.
