He emigrated the following year to New Zealand. He won another bronze in both the triples and fours in the 1980 World Outdoor Bowls Championship, but this time for New Zealand. The success continued as he won bronze in the triples and silver in the fours during the 1984 World Outdoor Bowls Championship. Moffat also secured a fours silver in Edmonton during the 1978 Commonwealth Games and a fours silver in the 1982 Commonwealth Games.

A gold medal finally came in 1988 when he won the triples at the 1988 World Outdoor Bowls Championship in Auckland.
