Rangitoto 'could blow again'
As reported on Stuff
Auckland's Rangitoto volcano could be set for future eruptions when it had been thought to be placid, new research suggests.
It was thought that Rangitoto was formed by eruptions 500-550 years ago but University of Auckland scientists now say it has erupted intermittently for a much longer period - about 1000 years until two major explosions about five centuries ago.
Lead researcher Phil Shane said it could blow again.
"We cannot rule out long-lived activity in the future, or eruptions at sites that have experienced previous activity.
"The Auckland volcanic field could be going into a new mode of operation. If so, we need to think about hazard planning and risk in a very different way."
The findings were important to understand the risks posed by volcanoes in the Auckland area and perhaps elsewhere, he said.
It was previously believed that basaltic volcanoes erupted suddenly in a new location each time, and only live for a few years, but this new finding was that they could be active over a much longer period than that, he said.
The information was found only because the researchers took an entirely new approach in their study.
Most studies use radiocarbon dating to determine the age of samples taken directly from a volcano, but these researchers examined ash in the sediments of nearby Lake Pupuke.
They studied the chemical fingerprint of tiny volcanic glass shards in the sediment that had built up over time and were able to determine when the eruptions occurred.
Human activity had disrupted the younger sediments in the lake bed so the scientists could not say with confidence whether there was any further activity at Rangitoto in the past 500 years, and they planned future work to address this.

Rangitoto Island Wrecks
The coastlines of Hauraki Gulf islands were once used as dumping grounds for obsolete ships. With rapid changes in technology, ships quickly became outdated and uneconomic to maintain.
Nowadays, obsolete vessels can be cut up and the materials recycled, but in the past disposing of unwanted vessels was a problem. The easiest solution was to drive them ashore where they would be out of sight, and leave them to rot or rust away.
Wreck Bay and the adjacent coastline of Rangitoto is a graveyard for at least 13 ships that were dumped on the island between 1887 and 1947. Read more>>

Saddleback nesting
The annual bird count has just been completed on Rangitoto Island and it is all good news. Researchers report seeing Saddleback and hearing Kaka and Kakariki. 15 Tieke were sighted, with 7 pairs, a single male bird has visited the Blue House on Motutapu. Also a female is using a nesting box and three other have made natural nests.

A summer place
Take a look at this documentary from 1995 in the TVNZ archive - it features many Rangitoto baches.
Synopsis: This beautifully-shot documentary is a social and architectural history of the great NZ bach (or crib for those south of the Waitaki). Maggie Barry tracks their evolution from workers’ cottages to a fully fledged icon in danger of extinction: as the blind eye turned by councils that made them possible becomes a thing of the past, and the coastline becomes too valuable to allow ‘just anyone’ to erect a shack on it. The Kiwi spirit that created the building is celebrated; and bach enthusiasts interviewed include Sam Hunt, Keri Hulme, Karl Stead and Rawiri Paratene.

Release of Takahe and Saddleback
Motutapu and Rangitoto islands were today (27 August 2011) officially declared pest-free wildlife sanctuaries following a successful eradication programme that first started 20 years ago.
They will now become home to takahe, with aims to have them house the largest population of takahe outside of Fiordland.
DOC has removed nine animal species from the islands. Possums and wallabies were eradicated in the 1990s. Ship rats, Norway rats, stoats, mice, feral cats, hedgehogs and rabbits have now been removed with the completion of a major eradication operation that began in June 2009.
To mark the occasion Conservation Minister Kate Wilkinson made the first release of threatened native wildlife on Motutapu Island - including two breeding pairs of takahë and 20 saddleback.
