Missing appointments could create a "vicious cycle" where warrants were issued and benefits cut, she said. "It's impacting their ability to be members of their community for simple reasons of it being difficult to access services."
The hub was designed to help those who were trying to move forward with their lives and get out of the "system", she said.
"It's not for the critically unwell and high-risk, or the people who are choosing to be in the system. What it is for is for those people trying to work or get their life back together and they are on the cusp."
Previously a Senior Sergeant with the Masterton police, Ms McKenzie said her time on the police force had helped inspire the idea of the hub.
"While I was a police officer, I saw people really struggling to get out of the hamster wheel - they are trying to manage multiple appointments with multiple agencies. If this can in any way get people back into employment and participating in the world, then that's a good thing."
Mayor John Booth said the hub was a wonderful initiative for Carterton. "It's bringing together all these groups under one roof and that makes a lot of sense."
Ms McKenzie said paint left over from the Events Centre had been used to repaint the house and furniture had been donated by some of the agencies involved, although they were still seeking a small fridge. Slots were still available for other providers.
Those interested in booking their appointments at Haumanu House were encouraged to contact the relevant agency.
- Haumanu House will be officially opened on Monday, May 2 at 10am by Mayor John Booth.
