Bit of apple glory, cultivated in the style of NZ variety (5,4)

I believe the answer is:

royal gala

I'm a little stuck... Click here to teach me more about this clue!

'nz variety' is the definition.
I know nothing about this answer so I can't judge whether it can be defined by this definition.

'bit of apple glory cultivated in the style of' is the wordplay.
'bit of' says to take the initial letters.
'cultivated' indicates an anagram.
'in the style of' becomes 'a la' (e.g. chicken a la King).
The initial letter of 'apple' is 'a'.
'a'+'glory'='aglory'
'aglory' anagrammed gives 'royalg'.
'royalg'+'ala'='ROYAL GALA'

Can you help me to learn more?

(Another definition for royal gala that I've seen is " apple".)
