Hello and welcome.
The skilled migrant visas are only available for those who apply under the age of 56 (so, from the fact that you mention being retired, this might not apply to you).
There are some retirement visas. Here's an information page about them -
http://dol.govt.nz/immigration/knowledgebase/item/1090. The main pages of the INZ website are a bit hit-and-miss at the moment, as they are being updated, so the link there doesn't seem to work. Here's a bit more detail about the Temporary Retirement Category.

If you apply for
any kind of visa at all, you will have to undergo the standard medical, and there is a section which looks at the BMI and waist measurement.
The INZ instructions for medical practioners state this.
The medical examiner is expected to calculate the BMI for all applicants aged 18 years and older.
Measure the waist circumference of all applicants 18 years of age. With a tape measure, comfortably
measure the shortest circumference that is below the rib cage and above the umbilicus.
The medical examiner is to request fasting glucose and fasting lipids where BMI >35 or when
the waist circumference in applicants 18 years or over is greater than the following limits1:
• men: ≥ 102cm, except Asian/Indian men: ≥ 90cm
• women: ≥ 88cm, except Asian/Indian women: ≥ 80cm.
Where a patient may be in a higher risk category, with fasting bloods having been requested, the
applicant’s attitude to their condition should be explored. Please note whether they recognise a
problem exists, whether they are planning any changes to improve the situation, have they made
any changes, what success, if any, have they had etc, is all relevant information.
