Testimonials

"The NSI Gel Polish training is fantastic. Provided in a professional and relaxed environment with our trainer giving each individual the attention they needed to trouble shoot and perfect areas they had trouble with. The course content is extensive and provides you with a good platform and knowledge to build your own clients from the very next day. The NSI products are also great and scientifically based - a dream to use."

"Blown away with the NSI NZ team!! Suzi looked after me very well and helped me to get to the point of putting my trust in another educator again. Thank you so much! You have no idea how much I appreciate your help! I have just done the Hard Gel course with Natalie. All I can say is WOW! Nat is amaaaazing at teaching and her approach to teaching 'real' things that you'll actually use is so helpful!! She's also so encouraging but also funny. Defiantly going to do further training as the products are great too!"

"I just completed the Gel Nail Application Course, everyone involved was friendly, full of helpful knowledge and they made you feel welcome as soon as you walked in. The customer service was 100% and I will definitely be doing another course with them. Thank you, I hope too see you sooner rather then later =)"

I completed a gel polish and simplicite' course in Jan, absolutely highly rate the simplicite' dipping system my clients love it, lasts fantastically, especially on hairdressers (which in my experience other systems have failed) onwards and upwards from here on in. Love it love it love it! Thanks team

Best nail technician course. I had so much fun and learnt so much!

Katherine, Christchurch

I completed the full nail technician course. I walked in with very little knowledge and left equipped with techniques, standards, and confidence. From the beginning of the course through to the end the most important thing was always "hygiene" and the customer. Creating a professional environment where the customer is valued, nails are looked after and cared for and the correct methods are used at all times. Thank you Natalie, Suzi and Kelly for my education. You made someone like me (who knew very little but knew I needed proper education) feel really happy, inspired and confident. NSI you have the right people working for you. I'm so grateful I was trained by the best. Macella :-)

Completed my nail training with Natalie from Nsi. Can't recommend her enough. She is patient, caring and a very very talented lady. I went with no knowledge whatsoever and came out with enough Confidence to start my own business up. Thank you to Lee and Suzi too for their support with enrolling me on the course.
