Married At First Sight NZ's Angel and Brett celebrate first wedding anniversary, tease baby plans

Brett and Angel Renall are celebrating their first wedding anniversary with touching messages to each other - and the exciting news they plan to expand their family.

The one lucky couple to stay together after Married At First Sight NZ's inaugural season tied the knot on August 17, 2017.

Angel says the relationship has gone from strength to strength and they're about to take the next big step.

"We are just about to buy our first home together and it has four bedrooms, so I guess we have to fill those," she told Newshub.

Back in November, she said she "definitely" would have kids with Brett - who added he was "100 percent keen".

The pair moved in together in December, in the South Island town of Lincoln. Since then, Angel says they've "learnt life" with each other.

"Working, paying bills, who does the vacuuming, where do we keep the sauce? Are tomatoes kept in the fridge or out? Generally you answer these questions before you get married - we were really in a bubble while we were on the TV show," she said.

"We knew the nuts and bolts we had were good and we have worked really hard at learning how each other works to keep it that way."

Angel says their getting French bulldog Cashew has been one of their "biggest highs ever".

The couple took to Instagram to mark 12 months since their wedding with sweet messages to each other.

"One year today! Crazy how fast it's gone but what an amazing first year. I'm so proud of everything we have achieved together," Brett said on his post.

"[I'm] so proud to be Angel's husband. She's the greatest!"

He added that she "understands" him so well, she knew the best anniversary present would be a donation to his favourite charity - Diabetes NZ.
