Abstract Drift cards were released in batches of 50 every 2 d at drilling sites off the north and south Taranaki coast (May-October 1975), Banks Peninsula (July-August 1975), and in Tasman (January-March 1976) and Hawke Bays (November 1975-January 1976). The shortest distance "despatch to recovery" trajectories indicate that only in the South Taranaki Bight are the trajectories predominantly unidirectional, the surface drift being southwards on the west coast of the North Island south of Cape Egmont. The trajectories of cards despatched in both Tasman and Hawke Bays highlight the variable nature of the surface drift in these bays.
