Instructor - $30 to $50 per hour but you need an instructors rating obviously. At $14K that is 280hrs to break even...
Ag work is paying up to $75K a year but its like Bell hater says: work 7 days a week and no time off. NZ has no flight and duty restrictions like the modern world and you are going to get ridden like that sheep...
Medivac/SAR guys on the 222 or BK seem to be starting at $75K and might be on 4 on, 4 off (if you are working the BK) or a similar type of roster on the Duece but expected to be on standby for the rest of the time on a pager. Funnel runs the 222 on a 24hr standby with 2.5 pilots. The 0.5 pilot is the manager. The BK guys are flying up to 90hrs a year and the duece is about 200hrs. Its boring and not that well paid compared to aussie or offshore for CHC, Abu Dhabi etc...
I am not sure about day rates for contract/casual guys but one North Is. tour operator paid $50 a day and $50 a flight hour. Only flying 1.6hrs a day on average means your 12hr day is paid at less than the award wage for being a waiter.
Consider your medical is costing up to $200 a year and twice that if you are 40, wear and tear on your car plus fuel at $1.80 a litre, no per diems (food), no health care nor retirement package, no loss of licence, no income protection and 12hrs a day for 6 days a week. Its FARKED!!!!!!!
