Sea level rise in New Zealand poses a significant threat to many communities, including New Zealand's larger population centres, and has major implications for infrastructure in coastal areas. In 2016, the Royal Society of New Zealand stated that a one-metre rise would cause coastal erosion and flooding, especially when combined with storm surges.[1][2] Climate scientist Jim Salinger commented that New Zealand will have to abandon some coastal areas when the weather gets uncontrollable.[3] Twelve of the fifteen largest towns and cities in New Zealand are coastal with 65% of communities and major infrastructure lying within five kilometres of the sea.[4][5] The value of local government infrastructure that is vulnerable to sea level rise has been estimated at $5 billion. As flooding becomes more frequent, coastal homeowners will experience significant losses and displacement. Some may be forced to abandon their properties after a single, sudden disaster like a storm surge or flash flood or move away after a series of smaller flooding events that eventually become intolerable. Local and central government will face high costs from adaptive measures and continued provision of infrastructure when abandoning housing may be more efficient.[6]
The results of studies from a programme called NZ Searise released in 2022, indicate that for some parts of New Zealand, the apparent sea level rise will be twice as fast as previously predicted. This is because of the combined effect of absolute rise in sea level with gradual subsidence of ground levels. [7] In some parts of Wellington, the land is subsiding by 3–4mm per year, leading to an apparent 30cm of sea-level rise in 18 years. By 2040, this is forecast to cause inundations every year that are equivalent to a 1-in-100 year event in 2020.[7]
