Three hundred mostly local crew are working on the 10-part series at a repurposed warehouse in Penrose and at multiple locations around the city.
Screen Auckland manager Michael Brook said Ash vs Evil Dead was major boost for the local industry.
"It's the kind of production that can really make a difference in terms of... providing good employment," he said.
"We're really pleased because it's another production involving Rob Tapert. He's done an incredible job in bringing an amazing amount of work to Auckland over the last 15 to 20 years," Brook said.
