Kupu Whakataki
He koranu parakore te nikara 201 mō te hokohoko, he rite ngā āhuatanga ki te koranu nikara 200, engari he iti ake te ihirangi waro hei karo i te pakarukaru o te waro i waenga i ngā poraka i ngā pāmahana tiketike.
He ātete ki ngā waikawa me ngā kawakore, me ngā hau maroke i te pāmahana rūma. He ātete anō hoki ki ngā waikawa kohuke i runga i te pāmahana me te kukū o te wairewa.
Ka matapakihia e te wāhanga e whai ake nei ngā taipitopito mō te koranu nikara 201.
