The rescheduling of Rugby World Cup matches because of earthquake damage in Christchurch means the Georgia squad will be arriving in Masterton one day later than planned.
Initially the team was to arrive on September 18 and use Memorial Park as their training base for the week.
Their stay will now run from September 19 to 25.
The venue change has made two modifications to Georgia's playing schedule. They were due to open their pool campaign with a match against Scotland in Dunedin on September 14 but that game will now be played in Invercargill.
Secondly, they were to meet England in Christchurch on September 18 but Dunedin will now host that game.
