'Ryan it's me!' - The moment a 111 call taker answered in his mentor's time of need

A St John call taker fresh on the job has told TVNZ1's Seven Sharp about receiving a 111 call they will never forget.

Ryan Glover was new to the job when he was surprised to hear a familiar voice on the other end of an emergency call.

The call was from his mentor Masina Ofa who'd just recently finished training him.

"All of a sudden, you could hear in the background - Masina must've heard my voice - and I heard this. 'Ryan, it's me! It's Masina!'" Mr Glover told Seven Sharp.

Pregnant with her fourth child, Ms Ofa had called requesting an ambulance, a call where the mentor had become the patient.

"I knew that I had to be the patient. I tried my best under the circumstances I was in, so stressful," Ms Ofa said.

After a successful birth Micaela Zinnia Ofanoa was delivered into the world, completing the mentor and trainee cycle with a personal touch.
