They could perhaps forego plush, sterile hotels for the cheaper, 'character-building' surrounds of a high quality youth hostel. The transport would be tuk-tuks, not air-conditioned buses.
Donning a cap in humid mid 30-degree temperatures and practising your craft on the low and slow dustbowls of an expansive maidan on a Saturday afternoon, just like Sachin Tendulkar did 25 years ago in Mumbai must surely hold allure. Alternatively, players could make their name among the plethora of clubs in the Colombo suburb of Cinnamon Gardens. New Zealand might see a return to innings like Stephen Fleming's 274 not out in a test at Colombo almost a decade ago.
A sustained spell in a club competition might be too much to ask. Another option could be schooling players at one of numerous reputable local academies, particularly in India.
The Herald on Sunday understands it would not be hard to strike up a relationship with a local association or to entice former first-class bowlers and other top quality tweakers to bowl at players in sustained net sessions over a fortnight for minimum financial reward. It would be an extension to what New Zealand has done in the past, bringing in the likes of former test players Saqlain Mushtaq and Chaminda Vaas for guidance.
The question of more experienced New Zealand players immersed in sub-continental provincial competitions is more difficult. As an example, India, unlike New Zealand, tends to keep a tight rein on allowing internationals players into the Ranji Trophy because it is seen as a sacrosanct nursery where they learn to play test cricket. Even Chris Cairns was apparently turned down in his pomp.
