He tohunga mātou ki te whakarato i ngā momo whakaritenga o te Paipa Rino Hanganga Porowhita, ki te mea he hiahia āu, tēnā koa whakapā mai ki a mātou, me te tumanako ki te mahi tahi me koe!
Ko ngā paipa maitai whakarewa LSAW ka hangaia mā te hanga pereti maitai hei ngongo mā te whakamahi i te tukanga whakahāngai JCOE, ā, muri iho ka whakarewahia mā te whakamahi i te pewa ruku taha-rua (DSAW) te hangarau whakarewa, ā, i whakaotihia mā roto i ētahi tirotiro me ngā maimoatanga.
Me pēhea te whiriwhiri i te tukanga whakaputa tika? He aha ngā rerekētanga me ngā painga o ngā paipa maitai kore hononga, te LSAW, te whakarewa pewa ruku, me te whakarewa pewa ruku? Ā, he aha te whānuitanga rahi o ia tukanga? Ka taea e koe te pāwhiri i te hononga e whai ake nei hei tiro.
