NZ's longest-married couple's advice to Prince Harry and Meghan Markle

Prince Harry is set to marry former Suits actress Meghan Markle this coming Saturday. 

To celebrate love and marriage, on Monday The Project heard from Kiwi couples who turned their weddings into a life-long love affair. 

"Our wedding day was on a nice, sunny day - and it was a memorable day because I got the girl of my dreams," said Maurice Tucker, who married his wife Gwen 76 years ago. 

Despite fewer Kiwis tying the knot, and Prime Minister Jacinda Ardern having a child out of wedlock, New Zealand has no shortage of love stories for those who said "I do" and stayed true. 

The couples shared tips on how to maintain a successful marriage.  

"Be open to discussion," said Tony Beveridge, who married his wife Mary 63 years ago. He said the secret to a happy marriage is to always listen to your wife. 

"Forget the sorrows of the past and live very happily together," advised Joan Lushington, who married her husband David 65 years ago. 

New Zealand's longest married couple - Auckland's Jeram and Ganga Ravij - say the secret to their own union is tolerance. The couple are turning 102 this year. 

The second longest marriage in New Zealand is Mosgiel couple Eric and Lillian Brinsdon, both 99, who celebrated their 80th anniversary in January.
