Cromwell couple Richard and Wendy Byrne, who also oppose the plans, said in their submission acceptance of the proposal would create "an undesirable precedent'', as it could spark "similar, high-density developments''.
Cromwell man David Lewis Holden, who supported the plans, said for Cromwell to keep growing it needed more sections.
The owners of Wooing Tree earlier this year applied to change the site's designation from rural residential to residential and light commercial.
Vineyard partners Geoff and Jane Bews and Steve and Thea Farquharson say the development could include community amenities, tourist attractions, retail and accommodation.
Ten percent of the development would be allocated to commerce, while the remaining 90% was for grapevines, residential lots and open spaces.
