She said there were various reasons parents didn't immunise children, including having several toddlers at home or struggling to get transport.
"We want to wrap support around them. We'll offer transport to our families where access is an issue."
She said the first target was those already registered with Tipu Ora but the drop-in clinic would be open to anyone.
With other services such as well child checks, dental services, smoking cessation and midwifery services in the same location, it made it convenient to do several things in the one place.
Mum of two Samantha Hughes said she loved the feel of the new drop-in clinic. While she always had her children immunised on time, Ms Hughes said the clinic being in the same place as other services she used would make it more convenient.
