Gallagher was enticed to come to New Zealand by his brother, Fergus, who has been working for Cambridge trainer Tony Pike for 2 years.
"Tony gave me a job, too, and I've been here since the end of September. He told me that if I got my weight down he'd give me opportunities.
"I've been riding work and at the trials for him and also had trials rides for Shaune Ritchie, Brendon Hawtin and Stephen Marsh.
"I've had about 25 trials rides and, though riding over jumps has been my bread and butter and that's what I love most, I'll be concentrating on getting as many flat rides as I can before winter."
Those trials rides include a win at Waipa on the Pike-trained Rippa Eagle, who has gone on to win his last two starts including his promotion from second at Ellerslie on Sunday.
Gallagher comes from a racing background with his brother Mark being a flat jockey in Ireland with international experience and his other two brothers also riders, while his father has been a foreman for a top Irish stable for many years.
Gallagher began his career as a jockey in Ireland with the legendary Dessie Hughes then shifted to England and teamed up successfully with Howard Johnson.
He won on his first ride at Aintree for Johnson and his CV includes two Aintree Festival winners and a Cheltenham winner. His most successful season was 2010-11 season with 26 winners when attached to the Johnson stable.
"I rode over 120 winners in England and three or four in Ireland," he said.
