Kua tata te mutunga o te tau 2018. I tēnei tau, kua piki haere te rongonui o te tukatuka taiaho, ā, kua piki haere te maha o ngā ahumahi tuku iho e whakauru ana i te tukatuka taiaho ki roto i ā rātou pakihi.
I roto i aua tikanga tukatuka taiaho, ko te tapahi taiaho te mea tino rongonui. I taua wā anō, me te tere o te whanaketanga o ngā mīhini tapahi taiaho, kei te kaha haere te whakataetae i roto i te umanga tapahi taiaho.
I tīmata te hokohoko o ngā mīhini tapahi taiaho i Haina i te tau 2000. I te tīmatanga, i kawemaihia mai ngā mīhini tapahi taiaho katoa i ētahi atu whenua. Whai muri i te whanaketanga o ēnei tau katoa, kua taea e Haina te whakawhanake i ngā wāhanga matua o ngā mīhini tapahi taiaho takitahi.
I ēnei rā, ko te nuinga o ngā kaihanga Hainamana e nohoia ana te mākete taiaho iti-mana, neke atu i te 85% te wāhanga mākete. Mai i te tau 2010 ki te 2015, i heke te utu o te taputapu taiaho iti-mana mā te 70%. Mō ngā taiaho reo-mana, kua tino angitu ngā kaihanga o te whare i ngā tau tata nei, ā, kua tino piki ake te wāhanga mākete, ā, ko te nui o ngā hoko o te whare i nui ake i te mea kawemai mō te wā tuatahi i te tau 2016.
Heoi, mō ngā mīhini tapahi taiaho kaha-nui, mai anō i te tīmatanga i kawemai katoatia mai i ētahi atu whenua. Nā te roa o te wā tuku me te kore pumau, me ngā here maha o ētahi atu whenua, ko ngā mīhini tapahi taiaho kaha-nui te mea i tino utu nui.
Engari i tēnei tau, i pakaru te mana o ngā kaihanga o tāwāhi i te mana o te taiaho kaha-teitei nā ētahi kaihanga o roto i kaha ki te whakawhanake i te taiaho kaha-teitei 1.5KW-6KW. Nō reira, e matapaetia ana ka heke te utu o te mīhini tapahi taiaho kaha-teitei ki tētahi taumata i te tau 2019, ka piki ake te whakamahinga taiaho i roto i ngā ahumahi tuku iho.
I te tere o te whanaketanga o te umanga tapahi taiaho ā-rohe, ka kaha ake te whakataetae i waenga i te umanga taiaho katoa i te tau 2019. Me tū motuhake ngā kaihanga taiaho ā-rohe mā te tuku i te kounga hua pai rawa atu me te ratonga whai muri i te hoko tere, me te take utu anō hoki.
