Finally I got my resident visa stamped in my passport. I have couple questions

Start Date is 18/Aug/2015 (When visa was stamped)
For the "first entry before": I have N/A

What that means?

In the same time my new CO sent me an email (Old CO left IPB office)

"Please see attached approval letter, note you must travel to New Zealand before 18/08/2016 to keep your resident visa valid"

And in the approval letter is stated

"There are two types of travel conditions on your resident visa. the travel conditions appear on the top tight-hand side of the visa label in your passport. The "first entry before" travel condition means that you must travel to New Zealand before order to keep your resident visa valid."

As you can see on my visa label "first entry before" is N/A

Also is stated
"When you travel to New Zealand in accordance with your resident visa, you must apply for and be granted entry permission."

What does that means? I should inform somebody before my first entry or?

PS. I expected blue sticker but it is green

Thanks
