Thankfully here with my GP he's super helpful and said if I brought in any forms or needed anything done he'd do it on the day so i can send it back asap, cheers for the reply lads. Thankfully I can just email the forms back as well.
Yep, the main function of a GP surgery is to provide primary health care.
Consider popping into the GP surgery from time-to-time and being polite and charming when asking desk staff about progress. One is more likely to get the process swiftly expedited than if one drips down the telephone about the delay.
Unsure what delays may be caused by the backlog associated with processing Commonwealth applications.
I'm not a Careers Adviser but if paper forms are being sent from the UK to NZ and do not arrive within a reasonable time consider asking if a PDF version can be emailed to you so that you can print them out and pass to your GP. I have no idea if this is even possible but it might be worth asking.
