Queenstown Airport Corporation chief executive Steve Sanderson said the main runway was resealed every 10 years as part of the airport's repair and maintenance programme.
The 2km-long runway was "milled" by contractor Fulton Hogan in 100m sections each night, and a new surface put on with the help of a pave set machine.
Mr Sanderson said before work began a month ago, 1200 letters were dropped in mailboxes advising Frankton residents of the resealing project.
There had been just one complaint, he said.
"We really appreciate the residents putting up with the noise. There was quite a bit of vibration noise overnight, but it won't happen again for the next 10 years."
During the work, the runway was closed after the final flight each night, with sections of 100m "milled".
Airport manager Chris Read said a mobile plant, owned by contractor Fulton Hogan, was used for the project. Sections of runway were mapped, using GPS technology, on a pave set machine which automatically determined which areas needed to be cut or filled to create a level runway.
Once the mapping was done the plant mixed about five different grades of gravels, from fine dust to thick gravel, to make Airport Mix 20, used for runways.
Sections were done once to level the surface and then again to build the thickness to 110mm, Mr Read said.
Mr Sanderson said the new seal was slightly thicker than the one it had replaced, which would be recycled and used to create a ring road around the inside of the airport landing area.
Each day a core sample of the runway from 30 different spots was sent to Alexandra for testing to ensure the pave set machine had the right measurements.
Mr Sanderson said the contractor would carry out a foreign object debris (Fod) check and then conduct an "emu parade, which is like a police line" to check further for any stray bits of debris.
Queenstown Airport staff would also complete a Fod check, he said.
Feedback on the new runway had been very positive, with pilots reporting it was a "nice, smooth surface".
