St Andrew’s Community Trust (SACT) works in connection with Waiuku and Districts Combined Churches and community groups. The trust exists to give encouragement, practical assistance and financial support for various community-focused initiatives. Funds are raised for these initiatives through donations and grants. All of SACT’s trustees are unpaid volunteers, and all funds administered are allied to community programmes.

Current initiatives include the following:

• Playgroup and mainly music (weekly programmes for pre-school children and their families)
• St Andrew's Seniors (weekly programme for senior citizens) 
• Grandies’ Sandwich Club (support for grandparents with significant involvement in caring for grandchildren and possibly other family members also)
• English Conversation Group (English conversation skills for immigrants)
• Sunday @ St Andrew’s (monthly music concerts)
• FLORA FEST (annual botanical festival formerly known as Festival of Flowers) 

Other initiatives have included:

• Toolbox parenting groups and the 5 Star Families programme
• Men’s health event (planned to be repeated in 2025)
• Networking event
