The accent must have someone to do with that. Here on the east coast, at least where I am, CLARE and CLEAR don't sound similar.
KL-air vs. KL-eer
The New Zealand accent is notoriously flat and vowels are short in their pronunciation but there is a subtle difference, similar to what you say, however you would have to have superman hearing to notice it and be very proper in your phonation to say the two properly (i.e. differently).
Lots of names have more than one spelling; Katherine vs Catherine, John vs Jon, Thomas vs Tomas (latter is more a European spelling if I remember rightly), Loraine vs Lorraine, Graham vs Graeme etc.
Speaking of deciding to work as a Paramedic, I wonder if income ever factored into your decision making?
We spent three years at uni to reach Paramedic level and acquire a student debt of probably between $15,000 and $30,000; the salary is about $65,000 and after a couple of years you will be hungry to get up to Intensive Care Paramedic level so hopefully you'll get on the course and pass all the vivas and bits and pieces and your salary will go up to about $76,000 and then that's it, unless the union can negotiate a pay rise or you do a lot of over time /callback (carefully planned of course to stay inside legal driving hour limits) your earning potential will basically be static for as long as your in the Ambulance Service.
Nursing is the same, three years at uni and a debt of $15,000-$30,000 to start on mid $40,000's and your income potential is mid $60,000's but that is as a Charge Nurse working 60 hours a week.
In contrast my mate has just finished medical school, which is only two years longer, they start on $70,000 (give or take a few thousand) and after five years are on $90-100,000 (give or take a few thousand) and after seven years they are a Consultant on a minimum of $130,000 plus whatever else they can rake in in private practice (which is very good).
The average house cost here is over $400,000 and in Auckland $500,000 buys you a house in the ghetto with steel bars on the windows; fuel is just shy of $2.25 a litre, milk is almost $3 for 2 litres and a kg of ground beef mince is $10 or more.
People are often surprised to hear what the pay for various non-Doctor health careers and I tell you, the money is certainly not why I want to do it!
