Tonga's Minister of Justice says the number of couples divorcing is increasing, with some marriages lasting as little as two weeks.
Samiu Kuita Vaipulu revealed to Parliament new statistics showing the number of splits by couples aged between 20 and 30 rose from 205 to 245 in one year.
MPs expressed their concern at the figures, with one saying he had thought that Christianity and better education should help decrease the rate.
The number of underage or child marriages, with 68 such weddings in 2020/21, also caused concern.
UNICEF has condemned the practise of child marriages, saying they interfered with a girl's development with early pregnancy and social isolation, interrupting her schooling, limiting her opportunities for career and vocational advancement and placing her at increased risk of domestic violence.
The news came as Tonga's wedding season approaches.
Many families plan throughout the year for a wedding in the weeks leading up to Christmas and relatives and friends fly in from overseas for the celebration.
Tonga has also been a popular wedding destination for overseas visitors.
