Head teacher Dale Greene said some of the 40 children on the roll were coming from as far away as Middlemarch and Styx.
The kindergarten, staffed by one part-time and two full-time teachers, is licensed for 20 children per day but to date the only time the limit was reached was on Thursday mornings, Ms Greene said.
However, Central Otago Kindergarten Association manager Angela Jacobson said Tuesdays were also proving popular, prompting the association to consider changing the licence to cater for more children.
That could mean employing a third full-time teacher. She said the building was "definitely capable of hosting up to 40 children".
The Ranfurly kindergarten is the result of a two-year community effort led by the kindergarten establishment committee, which raised about $60,000 towards the $619,000 cost.
The Otago Community Trust gave $75,000 and the Central Otago Kindergarten Association initially gave $200,000, before later agreeing to fund the shortfall so the project could go ahead.
The kindergarten was built in Balclutha and trucked to the site in the grounds of Maniototo Area School about four months ago. Decks, verandas and landscaping were added before the formal opening on May 13.
Ms Greene said enrolments were being accepted for the waiting list - some parents wanted to get in early to ensure their children had a spot when they turned 2.
