More than 90 per cent of Kevin Andrews' free relationship vouchers are still in want of a couple and a couch, even though the trial period for the scheme is almost half over.

The Social Services Minister is urging couples to take advantage of a $200 voucher, especially over the Christmas period, which can be an "emotional and traumatic" time.

The government has been offering the vouchers to all committed couples over the age of 18, regardless of their marital status or sexuality, since July. Australian lovers are able to register for a range of sessions including on parenting, conflict resolution and financial management.

Mr Andrews's pet policy, which has been given $20 million funding for a one year trial, is aimed at preventing costly divorces. It is also part of his bid to ensure that Australians are ready for committed relationships and to have children.
