Clarke Gayford returning to MediaWorks with Fish of the Day

Clarke Gayford is being welcomed back to MediaWorks next year as his fishing show Fish of the Day will be broadcast on Three.

The broadcaster and partner of New Zealand Prime Minister Jacinda Ardern's return to MediaWorks was revealed on Thursday by the company, along with several other TV and radio announcements for 2019.

Fish of the Day is promised to take viewers on a journey to stunning locations where fascinating locals live, surrounded by some of the world's most amazing ocean ecology.

"2019 is looking great for Fish of the Day. Not only have we shot some of our best episodes yet, but we are really excited about our move to Three," says Gayford.

He's set to travel from the tropical South Pacific to the icy islands near Antarctica catching fish, learning about the species and location, and then unlocking secret, mouth-watering recipes.

MediaWorks also announced that Dancing With The Stars NZ will return in 2019, with Mike McRoberts and Matilda Rice confirmed as the first contestants.

Also coming to Three in 2019 is Patrick Gower: On Weed, a two-part documentary by Newshub's National Correspondent on the pros and cons of legalising marijuana.

Gower says he aims to "get to know more about cannabis than anybody else in New Zealand, then pass that onto the rest of the country" - and the timing could not be better ahead of a referendum on the issue during next election.

Perennial top-performing shows Married at First Sight NZ and The Block NZ will also return to Aotearoa's screens next year - the latter of which has been revealed to feature the makeover of four high-end Auckland CBD apartments.

Joining the reality TV fold is The Project's Kanoa Lloyd, who will host Moving out with Kanoa. The programme will follow New Zealanders as they embark on a move from their current house to something a bit less familiar - be that a tiny house, a boat or simply somewhere a little more rural.

MediaWorks also revealed it will air a two-part mini-series on All Blacks legend Jonah Lomu ahead of next year's Rugby World Cup. Mosese Veaila, 21, will play Lomu and show how he became the most recognisable name the sport has ever produced.

As for radio, MediaWorks has announced that TVNZ's Peter Williams is joining Magic Talk as a host, while The Rock's Drive show will be hosted by new duo Jay Reeve and Duncan Heyde, as Thane Kirby leaves the show.
