Tax cuts at a cost in Paul Goldsmith's mother of alternative budgets stuff.co.nz/national/polit… I think there is a typo in your story. The tax rate for 30% goes up to 90K.
This is not an economic budget but political bullshit. Say you are a fulltime worker at an hourly rate of $18.90 gets just $8.08pw ($420 pa) tax benefit under this scheme.

@drayeshaverrall Forget all the political rubbish. Do we have good experienced GPs. I am a brown migrant -KIWI for 25 yrs. Current GP is my 3rd (a Pakeha) has been him for 20 yrs. Of the previous 2 first was a crook- scammed the system, The 2nd was a moran. He did not know the difference ... @drayeshaverrall Between diarrhoea & Crohn's. I know accountants have a system of a verifiable ongoing professional development system built into their membership same with many professions I don't know what kind of professional development GPs have if any. 2/
