She said the expo was great, and had a lot of options, especially for different budgets.
Montgomery had been at the expo looking at options for a photographer, florist and a baker.
She said a highlight organising her wedding so far had been buying her black and red dress.
Rochelle Free, organiser and owner of Freestyle Events and Marketing Ltd, said the expo went well.
She said they had wanted to entice people to look at VR Rotorua Lake Resort because it was such an amazing venue.
"I think it's Rotorua's best-kept secret and a perfect place to have a wedding."
Free said they had also wanted to open it up to other wedding suppliers to make it a lovely time for everyone and show how amazing their weddings could be.
She said the expo included dresses, hair and makeup, hire gear to make tables, photographers, DJs, caterers, florists, a celebrant and a cake maker.
This was the first expo and it was hoped it would continue every year, getting bigger and better, she said.
Free said when people came to a show because they were getting married it was such a happy occasion, and so everyone was always positive and friendly.
