About 130 people attended a presentation on the plan (2GP) at Macandrew Bay on Wednesday night, after about 70 people had gathered in Mosgiel to discuss it on Tuesday night.
Another presentation was made in Middlemarch last night.
Council city development manager Dr Anna Johnson said the main emerging concern for the public appeared to be new rules designed to protect against land instability.
In Macandrew Bay, the 2GP would place some homes inside a new ''instability'' hazard zone, meaning extra restrictions on building activity that expanded the footprint of homes in the zone, she said.
The change would make such building activity a restricted discretionary activity, rather than a permitted activity, and geotechnical assessments would be required before construction took place, she said.
Otago Peninsula Community Board chairwoman Christine Garey said Wednesday's discussion focused on understanding the proposed plan's hazard mapping and how that affected Macandrew Bay.
It was thought ''several hundred homes'' could be included in the new hazard zones, and landowners feared geo-technical reports would be required for each affected property.
Residents asked council staff how the hazard zones had been decided on, whether by desktop analysis or by modelling.
Staff had explained both systems had been used, while also assuring homeowners financial implications were not expected.
''There was a lot of reassurance around the fact that it shouldn't affect insurance premiums.''
Ms Garey said the high turnout at the meeting had ''absolutely delighted'' organisers.
''It's such an important thing to engage in. Every property owner needs to check their property and the proposal's implications for their property.''
The community had appreciated the chance to meet council staff, she said, though response to the meeting's discussions was mixed.
''The feedback I've had is that some people were reassured and some still have a lot to find out.''
Dr Johnson was also pleased by the turnout, despite the concerns of some there.
''It was great to see so many people come out. We felt the meetings went well and had lots of positive feedback from people who attended.''
The council faced a no-win predicament, as it could not simply ignore hazard information if it knew there was a risk in the area, Dr Johnson said.
While homeowners might not like it, neither would prospective home buyers who wanted to be alerted to potential hazards, she believed.
''People don't like council telling them what to do in general ... You are damned if you do and you are damned if you don't.''
The plan's eight-week public consultation period began late last month and will end on November 24.
The 1600-page plan seeks to update rules for the management of land use across the city, setting out what people can do on their land and how it can be developed.
It is available as an e-document on the council website.
