The Turner Family Trust and others are seeking permission to reconstruct a jetty located on the southern foreshore of Lake Wakatipu, in the Frankton Arm.
An application to Lakes Environmental earlier this month said five families operated and used the jetty for recreational facilities.
"There are a number of significant safety factors that have been raised by the Southern Monitoring Group by both the Southern Monitoring letter and the experience of the owners of the jetty," the applicant said.
The area surrounding the jetty was dominated by dense invasive willow trees that had extended into the lake, causing local sedimentation under the root masses.
The new jetty would be 23.75m long and 1.6m wide, with small changes to height.
Written approval for the rebuild from six affected parties had been filed with the application.
