Does anyone know the potter who used this screw top mark?

After is bit of help here. This auction has a pot with a mark that I have been trying to identify the potter for, for several years.

As far as I can tell, the potter is from Auckland and is probably a woman working between the 1970s and at least 1990s.

Ev may know.

Thanks.

Sorry I don't recognise that style or mark, but there are distant bells ringing as if someone has asked this question before .....? Nice work!!
