Last month, RNZ reported that Japan had outwitted Sea Shepherd by expanding its whaling area at a time when its opponents' resources were stretched.
A Sea Shepherd spokesperson said the area was so vast it might not have the operating range to take action.
New Zealand or Australia should send a ship to intercept the Japanese fleet, the spokesperson said.
Failing that, the two countries could provide the exact coordinates of the whaling fleet so the organisation could mount a protest.
