"I chose this [ceremony] for the Maori culture, especially being Native American, there is so many similarities to the two cultures," she said. "We love it here, it is so relaxing and everyone has been so friendly."
Mr Mattos said the secret of their long marriage has been to laugh a lot together and "don't disturb her when she's packing".
"I didn't realise how special this would be. For me this caps it off, we have been travelling together for two months and we didn't even know we'd still be talking to one another at the end of it, let alone renewing our vows. This brings Rotorua into our lives forever," he said.
Mr Brown said the unique Maori culture was what attracted couples, like the Matttos, to take part in these ceremonies.
"When people come to New Zealand they like to experience the culture of the people, the city of love where the love story Hinemoa and Tutanekai came from. It's about walking in their footsteps. This helps keep our culture alive and strong and it's a pleasure to share that on this remarkable occasion," Mr Brown said.
