The National Party leader Simon Bridges is this morning addressing the media in response to Treasury's claims of a "persistent and deliberate hack" of its systems. Yesterday National leaked what should have been secret budget information, but refused to say where it had come from. So how was such highly sensitive information compromised? Kathryn Ryan is joined by RNZ's political editor Jane Patterson and Tony Grasso who is the head of technology at Cyber Toa - a cyber security consultancy. Before that he was head of engineering and R and D at a sensitive government agency and also the cyber lead at the Department of Internal Affairs.

Co-author of "The Law of Insurance Claims in NZ", specialist insurance lawyer Chris Boys tells Kathryn Ryan why he thinks the property insurance market is "broken", and that risk-based pricing is flawed.  Kiwi insurer Tower was was one of the first insurers to shift to risk-based pricing, which it says is a fairer approach. Unlike IAG, Tower hasn't pulled out of insuring earthquake or severe weather-prone areas, instead it has made some policies more expensive.  Both Tower Chief Executive Richard Harding and Chris Boys agree central government needs to do more to plan for the effects of climate change so risks can be better anticipated.  Richard Harding also joins the conversation.

3D printed birds and fake poo are helping boost spotted shag numbers in the Hauraki Gulf.
