But on the return journey she "got stuck" in Fortrose.
"We tried several different routes but everything was closed. I could not believe the major flood in the region was happening in the week of my wedding."
Mrs Atley decided wait for "things to calm down" but the whole picture was not looking good.
On Wednesday, her prayers were answered when she met a couple from Te Anau who owned a helicopter.
"I did not think twice. I just wanted to be back to Invercargill where my wedding would be happening in few days.
Her dress even got a "VIP seat".
While she and her gear arrived safely on Wednesday night, the journey was not over.
"I forgot my veil in the car in Fortrose so my fiance's father had to drive there."
She missed other wedding appointments, including the hair appointment, but all the professionals made an effort to help her.
Due to batteries being flat on their phones the pair could not take pictures of the whole saga, she said.
"I'm really gutted. We just took one selfie."
Before she walked down the aisle, Mrs Atley said she was feeling "pretty relaxed".
She said it made her realise people "shouldn't sweat the small stuff in life".
