"This shows how important it is to start promoting mental wellbeing early in children's lives, so they can learn resilience. They can then apply these skills later in life."
The DHB said it had been putting extra resources into working more closely with community-based health providers.
This included providing education and peer support for GPs, practice nurses and primary care workers who support people with mental health needs.
To embrace this year's theme of doing something for mental wellbeing every week, staff from the Infant, Child, Adolescent Mental Health and Addiction Service were planning a team walk around Virginia Lake.
They'll also give out seedlings, donated by the Whanganui Garden Centre, with positive affirmations attached for clients coming through the service during the week.
Hawken said getting in touch with nature was an ideal way for people to lift their spirits on a daily basis.
"Whanganui DHB is keen to see its community take time over the week to enhance mental health and wellbeing, and embrace the theme 'Let nature in'.
"However, we also want to stress that you don't have to wait until October each year to make mental wellbeing your priority. Every week should be a mental health awareness week."
