Differing opinions on New Zealand First's member bill regarding the definition of 'woman'. 

MP Jenny Marcroft is proposing legally defining a woman as being an adult human biological female. 

Rainbow Auckland co-chair Sibyl Mandow says it's a political move to be divisive, stir up hate, and generate a narrative to distract from more pressing issues. 

Mandow says the bill is trying to denounce the existence of trans people – who have no agenda and just want to exist.  

But Speak Up for Women spokesperson Suzanne Levy told Mike Hosking polling on this issue indicates people don't want trans people to be treated poorly. 

But she says at the same time, people don't think sex can be changed. 

Levy says laws need to be definable, as sex has never had any other meaning than biological sex.
