MediaWorks group head of news Mark Jennings said this afternoon that Story would be a "smart, fun and thought-provoking show that will lead the way in daily current affairs".
"Story will focus on the issues that are relevant and important to all New Zealanders. We will be looking for the best stories, the most interesting stories and the stories New Zealanders are talking about," he said.
"Duncan and Heather are two of New Zealand's top journalists. They will be a formidable team at 7pm."
Garner will continue to present the RadioLive drive show, from 3pm to 6pm weekdays and Storywill be simulcast on RadioLive.
Garner said he expected fun, laughter and entertainment.
"I see this as a great chance to be part of a programme that will reflect our country and our lives - no matter where we live.
"And when those in power in Wellington, or in your own community, make bad decisions, mislead you or are hypocrites, I promise - you can rely on us to keep them honest - simple."
Du Plessis-Allan said she was excited to be part of TV3's "new chapter".
"Duncan is one of the best journalists around so I'm stoked to be able to learn from him. But Duncan, if you're reading this; don't let it go to your head. I'm not your sidekick. In fact, they told me, you're my sidekick."
MediaWorks chief executive Mark Weldon said du Plessis-Allan and Garner were two of the most engaging and talented journalists in the country.
"Together they represent a major investment by MediaWorks in the future of current affairs leadership in New Zealand."
John Campbell, who worked for TV3 for 24 years, has a new role as a presenter on Sky Sport, it was announced yesterday.
