The trees, one third of them kowhai, were planted by 25 pupils from nearby Carisbrook School.
Teacher Rachelle Moors said the pupils enjoyed the almost two hours they spent digging and planting at the park.
Dunedin Amenities Society president Paul Pope said the planting marked the third year of ``Project Gold'', a five-year partnership between the society and the Department of Conservation with the specific aim of having more kowhai planted in and around Otago.
Funding for yesterday's tree-planting event came from $7500 provided by the society for the five-year project.
Mr Pope said a different area was selected for ``Project Gold'' planting each year.
Sidey Park was chosen this year because the group knew of the hard work people from the Caversham community had been doing beautifying the area.
Pupils will also be able to grow their own kowhai trees using free ``grow your own kowhai trees'' kits provided by Doc.
