Hei kaihanga mekameka hononga maitai porowhita mō ngā tau 30, kua noho tonu tā mātou wheketere me te mahi i te wā tino nui o te whanaketanga o te ahumahi mekameka Hainamana e whakatutuki ana i ngā whakaritenga keri (ina koa ko te maina waro), te hiki taumaha, me te kawe ahumahi mō ngā mekameka hononga maitai porowhita kaha teitei. Kāore mātou e mutu noa i te noho hei kaihanga mekameka hononga porowhita matua i Haina (me te tuku ā-tau neke atu i te 10,000T), engari e piri tonu ana ki te auaha me te auaha tonu.
