There's a vision Australia and New Zealand can help ease each other's seasonal electricity woes. 

Company Taslink is proposing a massive underground trans-Tasman cable, allowing surplus power to be transferred between the two countries. 

It estimates the link would increase our power grid's capacity by about 40%. 

Co-Director Richard Homewood told Mike Hosking it would have meant 20% lower power prices last winter.  

He says Australia has the opposite problem, with power outages during the hot summer days, when we have a surplus.
