Kiwis have two more days to capture king tides hitting the country and help future-proof New Zealand against climate change.
Northland Regional Council (NRC) is asking people to take local photos of the effects of king tides on Northland's east coast this week, through to Thursday, and upload them to its website.
King tides are the highest tides of the year and happen roughly every seven months.
The Autumn king tides hitting New Zealand have occurred over several days in January, February, March and more will come in April as the sun, moon, and Earth align to create a strong gravitational pull on the ocean.
The height of these king tides is being amplified by climate change and sea level rise, and the NRC is hoping that helpful locals will take photos of just how high the tides are getting so that they can get a gauge on what the area could face in future.
"When king tides occur during floods or storms, water levels can rise even higher and have the potential to cause great damage to the coastline and coastal property," the NRC's website said.
"King tides give us a glimpse into the future of what Northland's coastline may look like as a result of sea level rise."
The NRC hopes citizens will get involved and take photos of the high tides to contribute to data monitoring and collection programs.
Their website gives these tips:
Find out the date and time of the next king tide near you. See the calendar for when these tides are scheduled to happen in Northland.
Visit your coast at that time and snapshot the tide at that moment. Get tips on how to get the best shot.

High tide is around 11:10am today in Whangarei, and midday tomorrow.
Looking ahead to April, the NRC wants photos from the east coast on April 9-11 and west coast on April 9-10.
In May, it wants photos from the east coast only, from May 8-10.
