Mark the Week: The maths trial results were an example of a simple truth

At the end of each week, Mike Hosking takes you through the big-ticket items and lets you know what he makes of it all.    Education: 8/10  The maths trial results this week were a tangible example of the simple truth that if you concentrate on something and work hard, you will win.    The All Blacks: 6/10  They did better than the critics seem to suggest. Rugby has changed but the attitude on expectation and winning hasn’t. This isn't 1986.    Regional councils: 8/10  Bold call, good call. We will be better off for the call.    Ginny Andersen and steak: 6/10  Who had her down as a surreptitious food stealer?    Rachel Reeves: 2/10  Have a look at her work on taxes and ask yourself how far-removed Barbara Edmonds is - or isn't.    Surrender by Thursday: 4/10  Wasn't that yet another harebrained thought bubble by a bloke who looks increasingly unhinged, or tired, or old, or mad. Or possibly all of those things.    LISTEN ABOVE FOR MIKE HOSKING'S FULL WEEK IN REVIEW See omnystudio.com/listener for privacy information.
