It was a response to requests for play equipment suitable for younger tamariki.
The funding will come from a $100,000 Placemaking Fund, created by the Far North District Council last year and split between the district's three community boards.
Stage one of the upgrade will use up Te Hiku Community Board's share of the fund for this year, just over $33,000, plus another $20,000 from its own funding sources.
Gardner said Jaycee Park was a priority because of its central location and popularity.
The community board aimed to add more features in future such as shade sails, drinking fountains, picnic tables, seating, lighting and concrete paths.
"Unfortunately, our funding does not cover all of these additions, so we're writing to local businesses and organisations seeking sponsorship to help pay for these."
Existing play equipment, including the train, will remain.
However, the future appearance of the whole area will be up for discussion when stage two of the revamp, aiming to improve connections between the playground and skate park, goes out for consultation.
