    The phase distributions of the M2 , S2 , K1 , and O1 tidal constituents around New Zealand are plotted from existing harmonic analyses of tidal heights. Both semi-diurnal constituents exhibit a complete 360° range of phase around New Zealand, with complex areas of rapid phase change through or near the strait separating the two main islands. The K1 amphidrome and that for O 1 , which previously were thought to be centred on New Zealand, are shown to be located east of New Zealand. The distributions plotted highlight areas where tidal observations are lacking.
