Aotearoa New Zealand has an accurate and detailed record of past and ongoing coastal change, and an understanding of its causes to support projections of future change.
We currently have an incomplete knowledge of how our coastline is changing, where and at what rate. Coastal erosion is a significant hazard facing coastal communities throughout Aotearoa New Zealand. The risk exposure of coastal communities and infrastructure is rapidly increasing as sea-level rise accelerates and a legacy of poor coastal planning decisions takes effect.
We are creating a national coastal-change database to understand the nature and causes of past changes and to maintain a record of ongoing changes to help anticipate the future. To achieve this, we are:
Our goal is for our publicly available database of past and ongoing coastal change to be used by planners and decision-makers when deciding how to best plan for our changing coastline.
He pūkete tōtika, āmiki hoki tā Aotearoa mō te hurihanga haere o te takutai, me te mārama anō ki te pūtake me te tautoko i ngā matapae o ngā hurihanga anamata.
Ināianei he hukihuki tā mātou mātauranga mō te hurihanga o tō tātou takutai, ki hea, ā, pēhea te tere. He mōrearea nui te ngāhorohoro o te takutai e pā nei ki ngā hapori noho ki tai puta noa i Aotearoa. Kei te tere piki haere te pānga o te tūraru ki ngā hapori noho ki tai me te tūāhanga hoki i te tere o te pikinga o te paemoana me te pāpātanga o ngā whakataunga whakamahere koretake o mua.
E waihanga ana mātou i tētahi pātengi raraunga mō te hurihanga-takutai kia mārama ai ki te āhua me te pūtake o ngā hurihanga o mua me te pupuri i tētahi pūkete mō ngā hurihanga moroki hei matapae i te anamata. Hei whakatutuki i tēnei, e pēnei ana mātou:
Ko te whāinga mō tā mātou pātengi raraunga tūmatanui mō ngā hurihanga takutai o mua, moroki hoki, ka whakamahia e ngā kaiwhakamahere me ngā kaiwhakatau i a rātou e whakatau i te ara tika hei whakamahere mō ngā hurihanga o tō tātou takutai moana.
