Option for day-night first-class cricket in New Zealand are limited to those three venues.
There are no lights at Dunedin's University Oval, Hagley Oval in Christchurch, or Wellington's iconic Basin Reserve.
Wellington's Westpac Stadium has lights, but is seen as a limited-overs venue only, never having hosted a first-class game.
Pakistan (two tests next November), Bangladesh (two in December) and South Africa (three in February/March) are the incoming tourists next summer. November is thought too dewy at night; ditto, with Super Rugby well under way in February, there's similar climatic concerns.
Should the Adelaide test prove a fizzer in playing terms, or the Plunket Shield games not work, and player feedback is poor, things might change.
But NZC chief executive David White said yesterday, there is significant interest when there's a mood for change in the first-class game.
"In debate around the ICC's chief executives' table, there's been a lot of interest," he said.
"Everyone acknowledges outside England and Australia it's a big challenge getting test crowds. Certainly it's a concept we've be very receptive to."
However, NZC won't commit to a headlong march down the pink ball highway if enough question marks hang over it.
