The helicopter arrived at Whangarei Hospital at 6.40pm.
Mr Going said the skipper, a Northlander, injured himself in mid afternoon but how it happened was not clear.
He said the man and two others headed out for crayfish but had to turn around and go towards Houhora when the skipper was hurt.
The injured man's condition was not available at edition time yesterday.
This year is the busiest on record for the Northland Rescue Helicopter teams who have responded to 466 requests for help to date, up from 404 for the same period last year.
During a week-long period in early August there were 32 flights, 10 of which were at night, plus two missions that started in the day and ended at night.
