I am confused over these two different shortage lists.

My husband has a degree, 2 years teaching, 18 years gas fitting with full City & Guilds apprenticeship but on the points indicator without a job offer still only scores 75.

What I don't understand is that gas fitting is on the occupational shortage list throughout NZ but not on the priority shortage list. Am I completing it correctly or should my hubby be able to claim extra points for being on the occupational list?

He actually starts sub-contracting as a gas fitter tomorrow after a break from the industry for 6 years - don't know how he'll cope without all those holidays
