Martin started the season as the dual coach of the Kaikorai premier side and the Otago Boys' High School First XV. He also works fulltime as a teacher at Otago Boys'.
But his workload increased again when he accepted a coaching role with the Otago national championship team.
Something had to give, so Roger Cotton has taken over as head coach at Kaikorai. Martin will remain involved, albeit in a reduced capacity.
"Obviously, I'm wary of the current workload I have," he said. "But it is good for me because I think it sharpens you up as well.
"I still help out [with Kaikorai] on a Tuesday and try to get to as many games as possible. I also help with the analysis side of things as well, so I've still got a reasonably big role.
"They've got a very young team up there and they are going pretty well to be fair. Bar a couple of last-minute losses we'd be sitting in second place on the table."
Kaikorai is in sixth place with a record of two wins and four losses.
Otago Boys' has returned to the Otago premier schools competition this season and opens its campaign against South Otago High School at Forsyth Barr Stadium tomorrow.
The team will be hoping for a better start than it had on Sunday for its interschool match against Christ's College at Littlebourne. The game was a 24-24 draw but the home team started with 14 players after getting a yellow card for crossing the 10m mark during the haka.
The penalty was introduced this year to prevent the sort of scenes witnessed last season during the traditional fixture between King's High School and Otago Boys'.
King's crossed the 10m line while performing the haka and Otago Boys' took exception to the breach. Three Otago Boys' players ended up being suspended for separate incidents but two of them were related to foul play immediately following the haka.
