"If they don't get the right kind of help, they may feel quite damaged for some time."
Luke and Lacey were the first couple to call it quits after a tense cocktail party during which Lacey accused him of being fame-hungry.
The newlyweds were followed by Claire and Dom, whose marriage fell apart when Dom sent a frustrated text message about his wife to her, instead of his mate.
The third fail was Haydn and ex-The Bachelor NZ contestant Bel. The couple disappeared off the show after producers had to intervene and break up a verbal stoush between Haydn, Ben, Vicky and Andrew during a dinner party. The incident came after revelations that Vicky and Haydn were exchanging messages on social media despite not being a matched couple.
Things were turbulent for two of the remaining three couples in the most recent episode.
While Brett and Angel remained head over heels in love, newlyweds Ben and Aaron continued their rocky relationship with Ben questioning his husband's trustworthiness.
Meanwhile, Vicky was excited about being apart from husband Andrew for a week, who remained hopeful despite the show's experts warning him he appeared to have been "friend zoned".
Wallis said in general, if someone didn't learn from bad decisions in a relationship, they were likely to repeat them. She said those on the receiving end could be highly anxious and mistrustful going into a future relationship.
Wallis said it was also possible the cast members would question the authenticity of people, such as potential partners or friends, much more now they have become well known.
When it came to the contestant's professional careers, Duhs said if someone acted badly on the show the experience could affect their job.
"I'm sure it will affect some of them for years actually, to be honest. I know that being on television in New Zealand is something people remember and if they have acted in ways they regret on television it may be very hard for them to move past that perception from other people," Duhs said.
"People would likely remember [how they acted] and could interact with that person differently."
Relationship expert Alastair Duhs' advice for the failed couples:
1) Take time to process the experience
2) Make a short term plan to move on, including focusing on your own life and moving away from MAFS
3) Focus on what you have learned from the show
4) Surround yourself with your social circle again
5) Try to think positively about the experience and the future
