[5] Between the special and third series, a sixteen-episode digital web series and public service campaign by New Zealand Police to inform the public on health, safety, and best practices during the COVID-19 pandemic, titled Important COVID-19 Messages from Wellington Paranormal, began airing from 26 March 2020, featuring Andrew Coster and Clarke Gayford as themselves.

[24][25] In the United States, the series debuted on The CW on 11 July 2021, with episodes available to stream on HBO Max the day after they air.

The site's critical consensus reads: "A deft blend of monster-of-the-week frights and low-key humor, Wellington Paranormal is a droll delight.

"[31] Clarke Gayford's appearance on a short Wellington Paranormal video in April 2020 encouraging people who were looking after young children during the COVID-19 pandemic drew some criticism due to his relationship with Prime Minister Jacinda Ardern.

National Party Member of Parliament Brett Hudson alleged during an Epidemic Response Committee meeting in early May 2020 that the video risked "politicising" the New Zealand Police.
