Two-and-a-half-thousand junior doctors have been striking since 7 this morning over pay negotiations.

The Resident Doctors Association says the latest offer meant about 600 registrars would have had pay freezes or cuts of up to 12 percent.

Health NZ Chief People Officer Andrew Slater says no current resident medical officers would get a pay cut.

"That's the reason we're going to facilitation that was granted by the ERA last night, so that we can get a facilitator to help us understand why they believe that's the case. This is a good offer on the table."
