You can do things with a British passport you can't with a NZ passport, and vice versa. NZ consulates for example can be quite weak, if they are even there, so if you travel certain places you are better traveling on a UK passport. Three passports is even better for options.
If you never travel, you don't even need one passport.
As for being "committed to NZ" what does that mean anyway? Has it something to do with more than rugby?
