SFNZ chief executive officer Jo Lambert said ST's services would not lose any funding under amalgamation, and would get a share of other funds.
Replying to questions from the floor, Ms Lambert said each region offered different services.
There were swimming groups in Auckland and singing groups in Hamilton.
Gisborne would not lose any services.
“We will be encouraging the level of involvement you have had in the past.”
There would be new services.
For instance tablets and tablet literacy was being trialled elsewhere.
ST president Jan Ewart, speaking before the AGM, said there were many benefits to be gained from joining New Zealand's national stroke organisation, while maintaining the local workforce, services, and community connections.
Both bodies have entered into a Memorandum of Agreement (MOA), with the merger planned to take effect from December 31.
The current ST committee will continue until the amalgamation is completed
Ms Lambert said there was a process and the entire transition could take 12 months.
