The artworks were to be auctioned off at the Tauranga Sunrise Rotary Club Treasured Art Auction, which raised money for Graeme Dingle Foundation's Kiwi Can programme.
The Incubator provided the material and plenty of guidance.
Mr Brownless said he was not much of an artist when it came to painting or potting.
"I'm taking it gingerly, while Simon went in bold," Mr Brownless said, eyes glued to his canvas as he delicately tried to make Frida's nostrils less menacing.
He did not expect to break any auctioning records with his artwork - "although it might break the record for lowest priced artwork ever sold."
Mr Brownless said it didn't really matter, "it's all for a good cause and I've had a fun time."
Mr Muller said it was an intense activity and required serious concentration.
"I had planned to do a picture of Mauao and was quite confident I could pull it off but I didn't expect we would have to do a portrait of Frida Kahlo."
Mr Muller was showing his creative side as he said he loved the way smoothing the pastel changed the texture and softened the painting.
"I've loved doing this today."
Rotarian Kathy Webb said the politicians' artwork would join around 60 pieces of top quality art donated to the auction.
"We make quite a bit for Kiwi Can every year - last year we raised $13,000," she said.
Rotarian and Incubator trustee Ken White said the Incubator wanted to show people art could be for everyone.
They got involved with Saturday's event to grow awareness of what they do - art classes, art exhibitions and boot camps.
Mr White said they would be running boot camps with drawing and pottery for team building.
