Firstly

to the forum. The expo will give you a load of info and an indication as to whether your skills are needed. Have you checked out the
Long Term Skill Shortage List on INZ. Not sure if accountants are needed but nurses certainly are. You could also try the points calculator
Points Indicator to see if you will have enough points to try for the Skilled Migrant Category. Age should not be a problem - if anything you get extra points the younger you are. With regards not being married you just have to prove you are in a stable relationship and have been for more than 12 months.
Who will be the principal applicant? If it is your partner she won't be able to apply for PR or actually work in NZ until she has NZ nurse registration. For this she will need her UK registration first. NZ registration can take from 3 - 9 months which will give you an idea of the timescale you would be looking at.
Please ask away if you need any more help. Good Luck
