Its both easier and harder in some ways. What we know is that bananas tolerate a wide range of conditions. But they do not like the cold or the wind.
That said, a number of bananas are being grown across the warmer and more sheltered parts of NZ from North Taranaki to the East Coast and Gisborne, from Hawke’s Bay to Martinborough, from Palmerston North and Feilding to Whanganui. Northland are already into a commercial quantity and others will follow soon.
