Do you still do more hours (200)on the modular course compared to the integrated (150)? As a product of the modular course I don't have much experience with the Integrated course. What I do know though, is that flying around NZ with a NZ PPL visiting as many airfields (patches of grass and gravel) as possible within the rules was the best time I've ever had when it comes to flying. Taking your mates to critique / give random failures to you also adds to the experience.
CTC NZ are getting more and more instructors qualified to instruct integrated students so the any delays between the 2 courses should start to level off.
