OK, there's something on the city and county Dept of Parks and Rec page:

May 27 - Following Mayor Caldwell's Restore Honolulu 3.0 Order, the Koko Head Tramway reopened the afternoon of Tuesday, May 27. City off-leash dog parks and skateparks are scheduled to reopen on Friday, May 29. On June 5, the City will be re-opening the
Koko Head Shooting Complex, archery range, People’s Open Markets (POM), and swimming pools for lap swimming only. The Honolulu Zoo is also targeting a June 5 re-opening. A re-opening date for the Hanauma Bay Nature Preserve has yet to be determined.
With restrictions lifted on outdoor gatherings of 10 people or less (regardless of household), park activities that do not require a permit will be allowed during normal park hours with physical distancing of six feet or more being observed. Sports league activities are not currently allowed, though the City is pursuing a path forward to allow organized activities of this nature to resume at City parks.City gymnasiums, campgrounds, playgrounds, and other indoor and outdoor City park facilities not already reopened (such as stand-alone comfort stations and Community gardens which were previously reopened) remain closed at this time.
