NZ’s landmass overall is rising slowly with an average GIA of around 0.3 mm/year of relative sea level.
Will NZ go underwater?
New Zealand, meanwhile, was part of a young continent forming a thin tectonic plate and so most of it has hardly any “anchor” to hold it down. With the same anchor as Australia, New Zealand would be more than 1km underwater .
Will NZ ever sink?

Is New Zealand in danger of rising sea levels?
Sea levels around New Zealand have risen by up to 220 mm in the last century and are expected to rise by a further 300–400 mm in just the next 30–40 years. ...
Is NZ rising or sinking?
NZ’s landmass overall is rising slowly with an average GIA of around 0.3 mm/year of relative sea level.
How high will the sea rise by 2050?

What cities will be underwater in 2050?
Most of Grand Bahama , including Nassau (pictured), Abaco and Spanish Wells are projected to be underwater by 2050 because of climate change.
Which continents are sinking?

How much of NZ is underwater?
The landmass is 94 percent underwater, with just the islands of New Zealand and New Caledonia poking out above sea level.
Is most of New Zealand Underwater?
About 94 percent of Zealandia is underwater with the only above water landmasses making up a few Pacific islands including New Zealand.
Is Australia going to sink?
Recent measurements using the Global Positioning System (GPS) suggest that the Australian continent is sinking , but current understanding of geophysical processes suggests that the expected vertical motion of the plate should be close to zero or uplifting.
Can New Zealand survive climate change?
New Zealand was found to have the greatest potential to survive relatively unscathed due to its geothermal and hydroelectric energy, abundant agricultural land and low human population density.
Will Auckland be underwater?
Auckland. The entirety of Auckland’s Wynyard Quarter could succumb to the sea , as would areas of Parnell and Point Chevalier. Helensville would be no more, and Parakai would suffer too. Large swathes of the North Shore and Onehunga are all at risk of flooding as is the coastal areas of Mangere.
Will New Zealand be underwater global warming?

A 25m sea-level rise would displace 43% of New Zealand’s population (1.8 million people)*. The 80 metre scenario represents complete melting of the Earth’s ice sheets and major glaciers.
How can we stop sea level rising?
- Reduce your footprint.
- Protect wetlands. Wetlands act as natural.
- Let it soak in. Hard surfaces prevent water.
- Plant more plants and save trees. Plants.
