It is difficult to know if it is not there and the data of such a beautiful and great Nation are handled; However, in the ad hoc Ministry or in the New Zealand Health System you will be able to find such data ... but, on the other hand, I do not believe that they do not follow the general trend - unless you tell us otherwise and why - regarding to the countries around them and their level of economic and psychosocial development, otherwise the Scientific Health Community would know something about it. I myself - and I am sorry for what might seem petulant - am an Adviser to the WHO and do not have and have not found any special data on this.However, check with the Gynecological and Obstetric Association there or the College of Physicians and New Zealand Midwives.

You can check my paper out if it get you any ideas:

This is something the MOH in NZ can provide.
