An enterprising Dunedin company is selling T-shirts featuring the image of Dr Ashley Bloomfield for the sake of charity.

"Immortalise NZ's hero of quarantine and grab yourself a sweet tee or tote bag," says the Facebook post from The Print Room.

Co-owner Jon Thom told Stuff said interest in the Director General of Health-themed merchandise had "gone very well" with hundreds of pre-orders since Wednesday.

All profits from the sales would be donated to New Zealand's Women's Refuge, meaning it would get $20 for each Bloomfield t-shirt, or $10 for a Bloomfield tote.

The company, which employs eight people, was in lockdown and he hoped to resume business when level 4 was lifted.

"When we are able to return to work, we will be producing and fulfilling all the orders."

The Bloomfield design was done by Dunedin graphic designer The Bold, and it captured his likeness well, Thom said.

"You see his face pop up all the time, and he is obviously a good looking man, which helps."

Bloomfield was a calm and reassuring figure, in a period of great uncertainty, Thom said.

"We are just trying to do something positive in a situation which is tough for business, but provides a great opportunity to raise money for charity."

The merchandise comes after actor Jordan Mooney – who played Eric on the television show Westside – starred in a music video paying tribute to Bloomfield posted on YouTube.
