Government MP Nikki Kaye has thanked the public for the messages of support she has received following her breast cancer diagnosis.
Ms Kaye, 36, says she received the "devastating" news on Friday.
"Thank you so much to the thousands of people that have sent me beautiful messages of support over the last 24 hours. It has been really overwhelming and very moving. I feel so grateful and loved that so many people have been so kind to send me a message," she wrote in a Facebook post.
"I want to particularly thank all of the people who have shared their personal story of fighting cancer, or caring for loved ones with cancer or people who are currently dealing with it. Thank you for your courage and kindness."
Prime Minister John Key says Ms Kaye is "young, she's very fit and she's very determined and she's a fighter so I'm sure she's going to get through this and be back with us".
Ms Kaye has asked for "a bit of space and privacy" while she undergoes treatment.
"I am trying to rest up so I don't expect to be able to respond at the moment but I aim to in the future. Thanks heaps xx," she said in the post.
