Ms Dawkins said the day helped showcase the park and introduce it to newcomers, who often returned by themselves days later.
Entry donations went toward maintenance and developments at the park, including a butterfly house, Mr Dawkins said.
As people walked around, Katikati's Chordial Quintet provided barbershop tunes while buggies helped transport people up and down main tracks.
Stephen Wood said he and daughter Katie, 2, had not known of the park and were blown away with what they found.
"I moved up from Wellington, saw it in the paper and all the guys at work talked about it, said it was well worth going to. And I'm really impressed." Mr Wood said he loved the amount of different activities on offer for families. Katie especially loved the alpacas on display.
"What was amazing was I couldn't get over the size of it. Once you get here, it's all day entertainment," Mr Wood said.
Children were offered the chance to go abseiling while green thumbs perused the flora and fauna. A team of volunteers has worked to develop the disused quarry, owned by the Crown, into a world-class park.
