The 30-year-old is spending the off-season on the Gold Coast with his family and is doing some construction work for a friend.
The Brooms have been in Australia since early April and are understood to be enjoying the lifestyle. However, the former Black Cap has not made a decision regarding his cricket career.
''Just weighing up a few things at this stage. Unsure what's happening next summer,'' he told the Otago Daily Times via a social website.
Broom has played 99 first-class games, scoring 5607 runs at an average of 38.66, including 13 hundreds.
He transferred to Otago from Canterbury in 2005-06 and has been one of the province's most prolific batsmen.
The right-hander is Otago's fifth-leading scorer of all time with 4617 runs at an average of 41.59.
Twelve of his 13 hundreds have been for Otago (the other was against Otago).
Only Craig Cumming (21), Bert Sutcliffe (17), Ken Rutherford (14) and Glenn Turner (13), Noel McGregor (12) and Aaron Redmond (11) have also scored 10 or more hundreds for Otago.
Broom, who played 22 ODI and 10 twenty20 matches for his country, also boasts an impressive one-day record for the province.
He has scored 2037 runs at 38.43, including three hundreds.
Otago Cricket Association chief executive Ross Dykes said replacing Broom, if it came to that, would be a difficult task.
''He has been a fantastic contributor,'' Dykes said.
''There is no ready-made replacement for Broom sitting out there but it is one of those things. Players retire, players get injured and you cope. And while he will be a hard man to replace, we're not badly off for batting cover at this point in time.''
Otago will contract its players in July and Broom has until then to make up his mind, Dykes said.
Broom's former captain Cumming said the batsman was looking at options after cricket and was interested in a career in the building industry.
He has previous worked on building sites and was keen to take up an opportunity to escape Dunedin's winter and get some work experience.
''I think the last four or five years for him have been very much about training, so I think it is a case of helping his career after cricket and also to give him some stimulation throughout the winter,'' Cumming said.
''I guess he wants to make sure, that when he chooses to finish playing, he has opportunities and has options available.''
