Mrs Meads said she wanted to do something to brighten up the days of parents and children who spent a lot of time in hospital.
"Sometimes you are there for months and months, so it is a burst in your day. Every day can be the same so anything that's a surprise is nice.
"It's just knowing [Love Letters] are putting a smile on a parent's face with a sick child and making a child feel good and making that hospital room a bit brighter."
Mrs Meads said the idea had gained traction on Facebook.
"I think there was a lady that posted it to a New Zealand teachers' page or something like that so it basically went out to 10,000 teachers a couple of weeks ago and created a whole lot more awareness."
She said she did not want Love Letters to be about her.
"It's very cool - of course the nomination is fantastic. Going forward the main thing would be to get more awareness that there are families in hospital with sick children, but knowing that people can achieve something to make them feel better just simply by doing a letter and sending it to me."
