As for names, the couple have several picked out. They are escaping to Queenstown in a fortnight for a babymoon break.
No name yet, though, on who will replace Street when she goes on maternity leave at the end of February. TVNZ is conscious of Street's public appeal and rapport with co-host Mike Hosking, and is eager to keep ratings up.
Next year, Street will be an unofficial ambassador for the Cricket World Cup, helping to get people excited and involved with the event, and particularly turning women on to the game.
She is a former Central Districts wicketkeeper, was awarded a university scholarship through the game and trained with batting star Jesse Ryder.
Seven questions of the week
1. Which TV household name can't hide his blatant homophobia? He fired off a missive to a colleague openly criticising gay relationships.
2. Shorty St stars Kerry Lee Dewing and Ria Vandervis, left, completed the Auckland half-marathon on Sunday. Feeling lazy?
3. MediaWorks boss Mark Weldon insisted the company's content launch party last week was all inclusive, but why weren't all RadioLive hosts invited?
4. With two stateside rugby tries, pin-up good looks and a code-swapping rep, how long before All Black Sonny Bill Williams ditches sport for entertainment? Will he become Hollywood's next action hero, a la Dwayne Johnson, Vinnie Jones and Arnie Schwarzenegger?
5. Who took Jim Hickey's scissors? Seriously, guys. They went missing from his desk last week and he sent out a furious email asking for their return.
6. Is this the best celebrity Halloween costume? Expat Kiwi thesps Claire Chitham and Zoe Bell, who call LA home, dressed inventively as "The Night Before" and "The Morning After".
7. Is this the most unappetising object you've viewed this week? TV star Nicole Whippy was given a surprise baby shower ... and this shocking birthing baby cake. Ick, much?
