The Far North unit's boat, named Coastguard Houhora, is second-hand, but its new crew are glad to have it.
"It's easier to train on a dedicated rescue vessel so so a couple of us who are qualified as skippers will work on getting all 12 to 15 members of our unit up to the high skill level required to operate this craft," Mr Gemmell said.
The 12 volunteers who went to Auckland were tuned up with lessons in navigation, search and rescue techniques, CRV handling and victim recovery.
Coastguard Northern Region chief executive Callum Gillespie said: "Preparing a Coastguard unit for operational readiness is no small task as no Coastguard vessel takes to sea without its crew well trained to cope with the conditions and the situations that they might have to respond to.
"The fact that we were able to send the Houhura team back to their base far closer to readiness and towing their initial rescue vessel was the result of a great team effort by staff and volunteers from around the Northern Region."
Between now and the start of summer, the Houhora team will be working hard to complete the remaining qualifications they need to be ready to assist their community when boaties start to return to the water.
