Lakes Environmental planner David Wallace had reported there was insufficient information to make a "valuable recommendation" concerning the appropriateness of the proposed development.
He wrote that while the proposed development was likely to have significant ecological, economic and community benefits, it would detract from Gibbston's existing character and amenity, and would not be appropriate based on the information Lakes Environmental had received.
Mr Wallace said the resort would cause "more than minor" adverse effects on water supply, access and roading, geological stability, flooding and debris flow, and traffic generation, although he noted further information was required to assess those effects fully.
He also reported the outlook and views from State Highway 6 and Kawarau River would be affected and the development was inconsistent with the partially operative district plan, according to the existing application.
However, Gibbston Valley Station general manager Greg Hunt, of Wanaka, said the company had spent two years on its "well thought out and comprehensive" application.
"Based on those requests of the planner to make an appropriate decision, we now have all that further information and it will be presented at the hearing."
Mr Hunt said it was important to note that no Gibbston resident had submitted in opposition.
GVS would call "12 well-recognised members of the Gibbston community" to speak in support of the development and say it conformed to the character of the zone.
A total of 18 consultants would also give evidence on behalf of the station.
"In our economic times, we are in a position to proceed with the development as we have no debt with any financial institution," Mr Hunt said.
"It's all funded by the partners of Gibbston Valley Station and we don't have anyone calling us in for money."
A total of 30 submissions were received by the deadline of August 13.
Up to 25 were in support, five were in opposition and 14 said they wished to be heard.
What does the proposed Gibbston Valley Station resort involve?
62 visitor accommodation units called "winery villas" in two clusters.
One cluster would have 24 two-storey villas behind the vintners market, the other would incorporate 38 units, six of which would be two-storey, to the east of the market.
30 two-storey golf course visitor accommodation units in a third cluster on the north side of State Highway 6.
There would be a spa, a range of two-storey staff accommodation units, maintenance areas and an extensive walking trail network linking with the community's Gibbston River Trail initiative, to create an additional 3km trail along the Kawarau River.
Consent was also sought to establish an 18-hole golf course, a golf pro shop, spa, restaurant and bar, a conference and function facility, indoor and outdoor swimming pools and hotel reception, plus roading, landscaping and earthworks within the Gibbston character zone.
A proposed vintners village would include a cellar door, a farmers market, a cafe, artisan workshops, the golf clubhouse and an information centre.
About 14ha would be developed as a vineyard.
Just over 100ha of the 405ha owned by Gibbston Valley Station Ltd (GVS) would be developed.
All the development would be in accordance with detailed design guidelines, which would be presented at the hearing this week.
There would also be 127ha of "ecological enhancement" areas covered by a GVS conservation management plan.
A draft plan was submitted with the resource consent application.
