If you'd still like to know about NZCLE, you can request their current info pack and this'll give you an idea about the 6 exams (NZLPE) that foreign lawyers generally must pass. Depending on where their legal education was obtained, length of practice and type of jurisdiction (common v civil), NZCLE may exempt a candidate from taking one or more exams an/or add requirements for doing legal course(s) at a NZ law school, and also do a post NZLPE course known as profs (about 18 weeks full time, I think). NZLPE exams are held twice a year, and may be sat in the UK. There's no requirement that all of them have to be taken at once.
Everything that remotely concerns law is very expensive here. That includes the assessment (I believe upwards of NZD 1,500), exams (each about NZD 500), profs (don't know the exact fees as I've been fortunately exempted) - etc.
