A spokesperson for telecommunications users says consumers shouldn't expect lower prices for iPhones but may get better deals on contracts when Telecom starts offering the device from Friday.
Telecom will be offering the new iPhone 4S on two-year contracts, three years after rival Vodafone became the first in New Zealand to do so.
Telecommunications Users Association of New Zealand chief executive Paul Brislen says there could be other companies lining up to offer iPhones.
2degrees says it has no immediate plans but cannot comment on discussions it may or may not have had with Apple.
Mr Brislen says the more competition there is, the better the deals consumers will get on contracts for the phone.
