However, MediaWorks did not comment on the future of the reality television series.
"7 Days is an integral and much-valued part of the Three brand and for New Zealand,
it is a local comedy institution," MediaWorks said in a statement to the Herald.
"The talent both behind and in front of the camera are simply best in class. Unfortunately, like all free to air content, it is not immune to the pressure we all face as industry in protecting and enhancing New Zealand and New Zealand stories on screen.
"And for next year, we have decided to rest the show for the first part of the year returning it in the back half of 2020 for a 12 ep run - timed around the NZ and US elections."
Speaking about Williams' show the network said: "NZ Today has been a great performer for Three and we have been thrilled with the response to it. However, in the same vein as our decision with 7 Days, we have had to make a tough call.
"Unfortunately this means we will not be renewing it for next year."
Williams told the Spinoff he was given little notice about the cancellation of his show and "shocked" by the announcement as he was meant to be applying for funding this week.
