Hi Mary. Welcome to the forum too!
I actually had really good results with one. Hubby and I were applying for a few jobs and even though we are quite good at writing and at first wrote our own using the links someone else gave above, I think we couldnt really grasp what was needed in a good NZ CV . Apparently the formats are quite different to UK and america.
Try King of Cv , give Arthur a call I think their website is still
www.kingofcv.co.nz - We both got jobs which was awesome and then my husband had his re written 2 years and got another job. Even our friends down in Wellington have tried them. We shopped around a lot and he gave the most personal service you could say and kept it affordable - very reassuring.
Remember you also have to be regularly applying for jobs etc! Stay positive.
