OECD report card on taxation

The Herald reports, Kiwis do better on tax.
Looking forward to some expert analysis on this and will post anything I spot (and certainly welcome any comments). The relatively low tax wedge seems to reflect our high level of income redistribution. Although the many other taxes we pay are not accounted for in calculating the tax wedge, a further finding shows NZ with the third highest percentage of total tax take being personal income tax. Suggesting that other taxation isn't comparatively high either. I wonder if local government taxes are accounted for. Their revenue is around ten percent of central govts.
