This event is part of the annual Festival of the Plain, which celebrates "living on the Taieri" and includes a Blue Light Disco this Friday.
Family groups enjoyed the live music at the Saturday party, which was held in the children's playground area at Memorial Park.
Participants also enjoyed a range of refreshments, including sausages and ice creams.
Some also tried out the bouncy castles, and were intrigued by some balloon sculptures.
The Fire Service demonstrated the use of fire hoses, and provided a safety display.
Event co-ordinator Ian Chalmers said the party had gone "extremely well".
No formal count had been kept but he believed several thousand people had attended throughout the day.
Entertainment organiser Robyn Taylor said hot weather had resulted in a much bigger turnout than last year, with many people staying on to 8pm.
Last year, overcast conditions had resulted in many people leaving early.
