As for my qualification

Qualification : Bachelor of Engineering with Honours
Subject : Mechanical Engineering
Awarding Body : The University of Nottingham, Nottingham, England, United Kingdom of Great Britain and Northern Ireland
Study Institution : The University of Nottingham Malaysia Campus, Semenyih, Selangor, Malaysia
Year of Award : 2011
Standard Programme Duration : 3 years full time

Assessment Outcome : A bachelor's degree at Level 7

Comments
In New Zealand, Bachelor Honours degree programmes involve a year of full-time study at postgraduate level and result in a qualification at Level 8 on the New Zealand Qualifications Framework. The above bachelor's degree with honours does not meet these characteristics, and is therefore most comparable to a bachelor's degree at Level 7 on the NZQF.

I hope my experience could help someone.
