The Block NZ host Shannon Ryan will not return

The Block NZ's Shannon Ryan has announced she will not return to co-host alongside Mark Richardson.

The Block NZ host Shannon Ryan has announced she will not feature on the reality renovation show when it returns to our screens next month.

The former music TV presenter has co-hosted the New Zealand series alongside Mark Richardson since it launched in 2012.

In a Facebook post, Ryan said she had been fielding questions about her return, before announcing she will not be back.

"Due to scheduling conflicts I won't be returning to the show however this decision has offered up some great opportunities to move on with. I've met some wonderful people during my three seasons on the show and while it is bittersweet to no longer be a part of the muddy madness, I am very much excited for what's in store for me next. ?#?onwards?"

Ryan recently married her American partner Justin Greenwood in an intimate Californian ceremony.

The pair met on Auckland's Piha Beach, while Greenwood was travelling around New Zealand, and now split their time between their two home countries.

Mediaworks has yet to confirm Ryan's departure or whether she will be replaced by a new co-host.

The Block NZ will return for a fourth season this year, with filming underway in the Auckland suburb of Sandringham.
