A picture painted entirely with an artist's period blood will be unveiled at an event in the posh Auckland suburb of Ponsonby on June 13.

The Menstruation Matters evening will host a range of speakers discussing the financial accessibility of menstruation products, along with Zoe James unveiling her artwork - which is entitled 'An Expensive Habit'.

Organisers say the event intends "to raise awareness of the struggles facing many females on a day-to-day basis and to demand that access to these basic items is provided to all those who need it".

Ms James says the blood required to create the art was all taken from one cycle - and she still has some left.

"I use a Mooncup and when I remove it, I have a small silicone cup that's full of straight blood - it's not like I'm having to juice it out of a tampon or anything. It's in its raw form," says Ms James.

She says the blood was immediately out into an air-tight jar and chilled, remaining sterile.

"Even when I open it now, it still doesn't smell. If you shove your nose right in the jar, it smells vaguely like raw egg".
