The dresses are made for two to 10-year-olds and given to discourage traffickers and predators from targeting the girls for slave labour and prostitution.
Ashburton Inner Wheel member Judy Kingsbury said seven members had been involved with making the dresses.
Another volunteer had made coat hangers and each dress also came with a handkerchief and knickers.
Each dress had a child age on it and also featured a card saying it was made by Inner Wheel in New Zealand, said Mrs Kingsbury.
Dress making material had been supplied and had been supplemented with surplus material from Inner Wheel members.
Each of the 30 dresses is unique and feature bright colours and patterns.
More dresses are likely to be made by the volunteers from Inner Wheel, said Mrs Kingsbury.
The Dresses for India project made and packed more than 6000 dresses in New Zealand between October 2016 and the end of 2018.
Dresses are delivered personally to the girls and transported to India by business Bed Bath and Beyond.
