I kawemai ngā kaihokohoko o Haina i ngā hua porowhita i mua i te wā, nā te mea e tumanakohia ana ka whakaitihia te hanga i te haurua tuarua o tēnei tau. E ai ki ngā tatauranga, ko te kawemai a Haina i ngā hua haurua-oti, ko te nuinga mō ngā hua porowhita, i eke ki te 1.3 miriona tana i te marama o Hune, he pikinga ia marama o te 5.7%.

Ko te mehua a Haina mō te whakaheke i te hanga maitai i tīmata i te marama o Hūrae i whakaarohia ka piki ake te kawemai o te maitai, ka whakaiti hoki i te kaweake o te maitai i te haurua tuarua o tēnei tau.

Haunga tēnā, i puta ngā kōrero ka whakakaha ake pea a Haina i te kaupapa here kaweake i te wā e whakaitihia ana te hanga hei whakarite i te tuku maitai ki te mākete o roto.
