I tēnei rā, ka kōrero tātou mō ngā āhuatanga o te whakaiti haruru mā te whakamahi i ngā pūwero.
Ko ngā pūtake haruru matua o ngā pūwero hau ko te tomokanga me te putanga. Ka taea e tātou te whiriwhiri i tētahi whakangā paipa e tika ana. Me whakamahi te putanga pūwero hau i te whakangā pore iti nā te mea he nui te pēhanga o te putanga me te tere o te hau.
