Te Utuhina Manaakitanga Trust, an alcohol and drug counselling service, was also at the event and provided a free barbecue.
Linkage community connector and one of the week's co-ordinators Derryn Hyde said the event was about bringing awareness to how community services could not keep giving without community support.
He said one in four people would experience a mental illness so the week was "bringing that awareness back, and breaking down the stigma and discrimination around mental illness".
Many of the activities this week reflect advantages of connecting with nature for good mental health and wellbeing.
The week's activities incorporate the Mental Health Foundation's suggested five ways to well-being which are give, be active, keep learning, take notice and connect.
