Women at Wellington's women's Arohata prison are working to make the most of Mother's Day this Sunday.
On any given day, around 20,000 children have a parent in prison - and a high percentage of the 75 women currently at Arohata are mothers. More than 600 women are behind bars in New Zealand.
For the first time, Arohata is making the day special with the help of inmates, who have created cards, baked cakes and designed a festive banner for the day.
A mother of two, who is expecting to spend another six years in jail, said special occasions like birthdays, Christmas and Mother's Day can be difficult.
"This is my second Mother's Day in jail. It's hard but it will be good this year that we're making a big deal out of it."
She said both her children were coming to visit on Sunday.
"I know my kids are okay but it's good to be able to see them, and see all the progress they're making, because they grow up so fast."
A 29-year-old inmate who has been at the jail for two years was also helping with the preparations. "It's nice to be able to do it for all the mums. The ladies they can't wait to see their families and their kids for Mothers Day it's quite special."
She said Mother's Day - along with custard at Christmas - were among the things prisoners most looked forward to.
Arohata assistant prison director Mathew Allen said it was shaping up to be one of their busiest days yet.
"We will have children, in with the mothers, filling in some cards that we've had created by the prisoners at Rimutaka prison. There will also be face painting for the children and other activities.
"The team have been working really hard with the women promoting Mother's Day on the site."
Mr Allen said there would be more than double the usual number of visits and up to three times the number of children.
Acting principal Corrections officer Stephen Bailey said being separated from family was hard on both the parent and child.
"It's not their fault that their parents are in prison, that their mums in prison, so it is difficult.
"I guess days like this just mean that it's an opportunity for the kids to get to spend some time with Mum."
Mr Bailey said building and maintaining relationships was an important part of rehabilitation for offenders.
