Yep Scott Maori Tv do very well giving us docs - although oldies still goodies.
Prime also have some decent ones at times - and at a decent hour!
Maybe now the TVNZ programmer has finally found left we might see some improvement.
If you want some decent crime drama - don't go past the British one - 55 Degrees North on Tv1 at 5 to 11 Tuesday nights.
I know it's good cos Tv1 always put anything non formulaic on when most people are asleep.
