Henry also said there was going to be "quite the bash" after her final stint on the 6pm news, and joked, "we've got a Kmart voucher somewhere for you" - a reference to news this week that John Campbell received a "shitty" bunch of flowers from the network on his final day.

Barry, wearing a red shirt, didn't say much during the broadcast. Henry even tried to cut Paula Bennett and Annette King off when they gave her a gushing goodbye.
But Barry's other co-hosts didn't hold back on social media, with sports newsreader Jim Kayes calling her a "wonderful mentor and friend".
Social media editor Verity Johnson said on Facebook that Barry was "the reason I didn't quit on day one".
Viewers also paid tribute on Twitter.
Even One News got in on the action, tweeting this pic of Bennett and King saying goodbye to Barry.
No official announcement has been made, but sources have confirmed Barry will be joining TVNZ's presenting team in the near future.
Barry's departure, revealed by the Herald on April 29, is the second high-profile casualty at TV3 in the past year after John Campbell left last May when his show Campbell Live was dumped.
In a statement, Barry said she was "looking forward to recharging my batteries and spending more time with my family".
