We're so excited to confirm the return of Ferndale favourites, Nick and Waverly.

Karl Burnett (Nick) and Claire Chitham (Waverly) will be appearing on Shortland Street after 12 years away. It's almost like going back in time. 

The couple are coming back to help us celebrate the 25th Anniversary!

Both actors agree that revisiting their old characters has been "heaps of fun." 

Although we can't reveal anything about their storyline just yet, "it's definitely going to be a fun watch," Karl says. 

The 25th Anniversary feature-length episode airs Thursday 25 May, from 7pm on TVNZ 2.
