Okoromai Bay is a picnic ground within Shakespear Regional Park at 1468 Whangaparaoa Rd, Army Bay, on the Whangaparaoa Peninsula in Rodney. It holds a 4.6 Google rating.
Picnic grounds beside the water live or die by the tide: at low water a bay can open up broad sandflats, which children love and wading birds work for food. Regulars plan around that, and arrive early on fine summer weekends to claim a table or a patch of shade, since coastal parks are often short on both. The usual regional-park rules apply: carry rubbish out, check fire restrictions in summer, and keep dogs where signage allows. None of it is complicated — just the sort of knowledge that separates a good afternoon from a sunburnt one.
Set at the seaward end of the peninsula, Okoromai Bay is the kind of place where a chilly bin and a free afternoon are all the gear you need.
