Hawke's Bay DHB still has a 'boil water' notice in place and the Hastings Council is still trying to identify the source of the contamination.

But what liability, if any, could the council face?

A group of US environmental and atmospheric scientists has joined together to bust a persistent conspiracy theory about chemtrails.

There are multiple websites devoted to the theory that the government or big business has been using jet aircrafts to spray chemicals from the sky to somehow control us..

A recent international survey showed Nearly 17% of people believed the existence of a secret large-scale atmospheric program (SLAP) to be true or partly true

So a team of scientists from different universities across the US conducted a peer reviewed study on chemtrails to debunk the myth and make this information available for anyone to see.

One of the authors was Steven J Davis of the University of California.

Tomorrow the government is holding official commemorations in Wellington to mark the 50th anniversary of New Zealand's involvement in the Vietnam War. More than 3800 New Zealanders served in Vietnam between 1963 and 1975, but tomorrow has been chosen as the date for commemoration as it is the 50th anniversary of the Battle of Long Tan, in which New Zealand artillery units were involved with Australian forces.

37 New Zealanders died in the conflict, which was the focus of many anti-war protests here at home.  Today Sarah Johnston from Ngā Taonga Sound & Vision is going to talk to us about recordings in the sound archives about the war.

3:10 Rabble: coder, activist and a little bit of an anarchist

Technology creates possibility and it should be doing more than making people rich says Evan Henshaw Plath, also known as Rabble.  

He doesn't just talk the talk about internet activism, he walks the walk.  

He was the lead developer at the company that eventually became twitter, but left when it veered off its original vision of creating a platform to help to organise activists.

Rabble is in New Zealand this week to talk about using technology to encourage activism and openness at the open source, open society conference.
