Hornblow claimed he held the homemade sign over the railing last night when Kuggeleijn batted and bowled before security swiftly approached him.
"I kept the sign down until Scott Kuggeleijn was bowling. I held the sign up again and around me unbidden, some of the crowd chanted "no means no," Hornblow said. "Not long after, two men came down from behind me and attempted to take the sign.
"A security guard appeared and said people had found my sign offensive and he was going to confiscate it, he did not accept my protest that it was legal, took it from me and left."
In a statement to the Herald, New Zealand Cricket public affairs manager Richard Boock said that the national body wasn't behind the removal of the banners and questioned the veracity of the claims.
"I can confirm that NZC, along with EPT and their contracted security provider P4G, did not authorise the confiscation of any banners or signs in last night's game," he said.
"In fact, we supported patrons by ensuring they knew the areas where banners could be placed without impacting on the commercial signage."
Photos of similar posters have since scattered social media, including one from Madeline Chapman, a journalist with The Spinoff.
Although Chapman's banner was not confiscated, she posted on Twitter that she was asked to take it down as it "covered the sponsor signs".
