(1), the cultivation of introduced semiaquatic tropical taro (Colocasia esculenta) on cooler southern Pacific islands during the Polynesian “initial colonization period” (ICP) (1200 to 1500 CE) represents a “striking” Neolithic example of nonoptimal, marginal crop production. In that respect, ICP taro pollen from Ahuahu, a warm-temperate, northern New Zealand (NZ) offshore island, is especially notable (1). However, the suggestion that NZ wet-taro cultivation “may have been confined” to such offshore islands (ref. 1, p. 8828) overlooks important mainland archaeological evidence (Fig. 1).
