"Everyone came back and they were all smiling and I asked what was up and they wouldn't tell me. I thought something was going on but that's the last thing I thought would happen. He said 'oh I have to get over the seat' and sat in front of me and as soon as he bent down on his knee I was speechless. The best thing that could ever happen," said Ms Anderson.
The Dargaville couple met at a New Year's party in Paihia seven years ago.
"We were on the way back from Paihia and I meant to send a text to my friend saying 'oh my God he's in the car, this is pretty cool' and I accidentally sent it to him and he caught on because I got his number that night. We just started hanging out together and one day he said 'do you want to be my girlfriend?'" said Ms Anderson.
Mr van Leeuwerden said Ms Anderson is the one who is motorbike mad. She has been riding since she was young.
"Renee is all in to her motorbikes, she got me into motorbikes. She kept taking off to the beach on a motorcycle and leaving me behind so I had to get my own," he said.
"I've been planning to go to Nitro Circus for years and years and finally made it when they came to Whangarei. It was the best night of my life," said Ms Anderson.
It's early days but the wedding is also looking likely to be motorcycle-themed with the bridal party riding in on dirtbikes and the bridesmaids and groomsmen wearing motocross gear.
