Kiwi star Brendon McCullum scored just eight on his debut as Glamorgan crashed to a heavy defeat in their C&G Trophy tie at Hampshire's Rose Bowl.
The 24-year-old flew in on Thursday as a five-week stand-in for Mark Cosgrove, who returns home for Australia A duty.
McCullum is a Twenty20 expert who will be used as a specialist batsman, Mark Wallace continuing as wicket-keeper.
"I'm coming over at the perfect time, next week's Twenty20 suits my style, I hope to make a contribution," he said.
The Welsh county are expected to use McCullum at the top of the order in Twenty20 as a direct replacement for Cosgrove, who has made a big impression this season.
"In New Zealand cricket I either open or come in at six or seven for a bit of a dig," said McCullum, who has appeared in 84 one-day internationals and 23 Tests, hitting 96 in his country's match at Lord's in 2004.
"I had just been sitting at home enjoying a bit of time off and starting to think about building up training for the new season.
"Then I had a call off [Glamorgan's Kiwi bowler] James Franklin, and a week-and-a-half later here I am.
"I hope to pick up my form quickly and get back on target.
"It's always been my ambition to play in Britain, but being known as a wicket-keeper my opportunities are few.
"But I think my batting is at a level where I can now be a real asset, and there's a great chance for me to develop that side of my game further with Glamorgan.
