New Zealand is presently in the early stages of realizing its signficant marine energy resources. The potential is impressively large: this paper addresses likely developments to harness this potential. Openocean wave and tidal current resources beenmodelled using hindcast techniques, resulting in an integrated suite of maps at national and regional scales. Specific prospective sites have been assessed by the simulation of three generic wave and two generic tidal current technologies at these sites. Tenyear power generation hindcasts enable assessment of the viability of specific sites and the potential
timetable and contribution of marine energy deployments to national energy supply.
