Even this extremely conservative report was suppressed by the previous Tory government
National
held back advice on 1.9m sea rise until after election while new
developments built

The National Government knew what the report said but held it going out before the election because it would demand they had an actual plan for climate change rather than the meaningless lip service they currently provide.
Let’s get this straight, the National Government held back a report showing no council should build near the sea because of a predicted 1.9m rise in sea levels and a new development got green lighted while they hid this report???
Drowning dreams: Billions at stake as Govt mulls sea level rules
Today, leading scientists recommend considering between double and quadruple that amount when planning new developments. The most up-to-date advice is codified in a new guide written by scientists and policy experts for the Ministry for the Environment.
That guide has no official status, but many councils know what it says, and the public learned of its contents when it was leaked earlier this year by the Green Party.
Based on the latest science, the guide says people should be planning for 1m of sea level rise for existing neighbourhoods, and 1.9m for “green-fields” developments or redevelopments that intensify land use in already built-up areas. The goal is to avoid adding lots of new housing to areas that might one day be flooded.
Yet, in the Coromandel alone, hundreds of new, permanent land titles have been created on low-lying coast in the past two years, after modelling at most 1m of sea level rise.
In 2015, Thames-Coromandel District Council approved a subdivision of 167 coastal sections after rejecting advice from flood experts at Waikato Regional Council to consider 2m higher seas. The district council factored in 1m, instead, noting in emails to the regional council that any updated government guidance wasn’t likely to arrive in time.
Two years later, the council allowed 72 new titles to be created along canals flowing from a harbour, again after modelling for a maximum of 1m higher seas.
These developments weren’t breaking any rules, or even going against best practice guidance, because the advice to factor in 1.9m higher seas was held back by the previous government until after the election.
The National Government knew what the report said but held it going out before the election because it would demand they had an actual plan for climate change rather than the meaningless lip service they currently provide.
That the National Government were prepared to damage so many peoples properties for such political gain is another ugly truth of the last 9 years under National.
Climate change needs planning now, councils warned, as Govt report reveals NZ's sea levels may rise by almost a metre by 2060
Local councils need to start planning now for dramatic sea level rise, a new report warnsTVNZ,
15 December, 2017
The stark warning comes in Ministry for the Environment advice to local government on preparing for "coastal change", and it's coupled with an admission by Climate Minister James Shaw that New Zealand "currently lacks a coordinated plan on how to adapt to climate change."
Auckland
underwater - sea level rise simulation shows areas worst hit by
climate change
This
simulation shows which parts of Auckland would be underwater at high
tide if the sea were to rise by three metres.
The
report, which was available to the previous government in May, says
New Zealand lacks a coordinated plan to weather the storms to come.
According
to Environment officials' projections, in a worst case scenario, sea
levels could rise by almost a metre by 2060. Within a century (2120),
that could be by as much as 1.36m.
Just
over 133,000 people in coastal areas could be affected.
ONE
News used Google Earth data to generate a simulation of which areas
would be affected by a three metre sea level rise – the areas shown
are approximate.
More
than 68,000 buildings are at risk - and the total cost of replacing
them is $19b dollars. That includes 382 "critical facility"
buildings, five airports, more than 1500 jetties and wharves, 46km of
railway and more than 2000km of roads.
The
hardest hit areas are in Canterbury and Hawkes Bay - with Waikato
having the greatest length of roads exposed.
Wastewater
treatment plants, potable water supplies and stormwater and overland
drainage systems will all be affected.
"Ongoing
sea-level rise will lead to irreversible impacts at the coast ...
because many land-use planning and asset and infrastructure decisions
made today have long lifetimes because of the permanency of
development (eg, subdivision, buildings and infrastructure), planning
for adaptation at the coast needs to start now," the report
reads.
It
continues: "Over time, however, communities will be left
increasingly exposed, with vulnerable assets and a stock of private
and public investment (eg, buildings, roads, utility services, sea
walls) for which difficult decisions will be required - remove,
relocate or demolish, or invest substantially to protect.
"The
places and environments valued by people will also be exposed to
increasing impacts, and vulnerable groups and those without the
capacity to move will be particularly affected.
"The
likely scale, extent and impact of the evolving increase in coastal
risk will be unprecedented across New Zealand."
The
report also says sea levels are expected to keep rising for several
centuries, even if global gas emissions are reduced, and we can
expect more dramatic weather events causing high tides.
If
the sea level rises by between 0.3 and 0.4 metres - possibly by 2050
- we can expect rare storm tide inundations to happen at least once
per year.
"In
New Zealand, by 2050-2070, extreme coastal water levels that are
currently expected to be reached or exceeded only once every 100
years (on average) will occur at least once per year or more."
Climate
Change minister James Shaw says the report shows "the size of
the task to build New Zealand's resilience to rising sea levels, a
warmer climate, extreme weather and other impacts of climate change".
"It's
important that New Zealanders have a clear picture of the potential
impacts of climate change so that communities, local and central
government, business and other sectors of our economy can make
well-informed decisions about how we build resilience and adapt,"
he said.
Mr
Shaw says the country is "in the early stages of planning"
but that it currently lacks a coordinated plan on how to adapt to
climate change.
