Wellington's response follows Fiji's announcement this week that it was hoping to establish a tourism bubble with Australia and New Zealand, to attract visitors.
Fiji Prime Minister Frank Bainimarama said tourists could be contained and prevented from mixing with locals.
"VIP lanes - starting on the airplane, then from Nadi Airport onto designated transport to their designated resort or hotel where they'll remain throughout their stay", Mr Bainimarama said.
Fiji was identifying geographically-isolated resorts best suited for the Bula Bubble, he said.
