Cricket statistician on how NZ qualified top for Test champs

Great news for our cricketers yesterday as they qualified for the World Test Championship final in England later this year. Australia's postponement of their tour of South Africa saw the Black Caps through to the final. In a statistical twist, it was Australia's slow-over rate in the Boxing Day test against India - whish saw them docked of four points from their world championship tally - that cost them the ability to qualify above the Black-Caps. Nathan Rarere spoke to cricket statistician Ollie Stevenson.
