Brown's third season with Otago came to an end on Saturday as his side crashed out in the Mitre 10 Cup Championship semifinal, going down to Bay of Plenty 48-32 in Tauranga.
Brown is at the end of his contract with Otago and in his three years in charge, the side has made the playoffs every year. It lost in the semifinals in 2015, lost the final last year and bowed out in the semifinals this year.
Brown said after Saturday's defeat he was not too sure what was in the future for him.
''At this stage I have not committed to anything in the future. I will just wait and see what happens,'' he said.
Brown wants to take the next step in his coaching career and move up into Super Rugby. With Jon Preston moving on from the Highlanders, there is an opening at the franchise.
Preston looked after player development and skills training and Brown would be qualified for that job.
He applied for the defence coach position at the Highlanders but missed out to Canterbury coach Glenn Delaney.
If Brown does get a position at the Highlanders, that would open up the role of Otago coach.
Assistant coach Tom Donnelly is just a few months into his coaching career but has impressed with the work he has done with the Otago forward pack.
Donnelly may get the job with some sort of assistance from a senior mentor, and a new assistant coach would be needed.
Otago Rugby Football Union general manager Richard Kinley said last week no discussion about the new coach would take place until Otago finished its season.
