"It's definitely something I'm monitoring," the 32-year-old said yesterday. "I'm working every day at the gym and making sure I do my rehab but I haven't felt anything [amiss] for about two months."
Four wicketkeepers have represented New Zealand this summer. Auckland's rising Glenn Phillips had five T20s; ND's Tim Seifert had four; Blundell had his two tests and three T20s; while Tom Latham seems the ODI fancy at present, having been keeper in all 13 home ODIs, tying in with dropping down to the middle order in that format.
Watling is aware there's a pack of eager, younger keepers queuing up behind him. Nothing like a spot of motivation.
"It definitely keeps you on your toes. We've got a good few young keepers coming through.
"Tom's a quality keeper and batter. Tim as well, and Glenn has played [for New Zealand] this summer as well. It's a good young crop."
Watling said it was best not to pre-judge what the pink ball might do on the drop-in pitch at Eden Park.
"The new pink ball obviously swings early but might flatten out, then it livens up again during that dusk period. It's just being aware of the situation, where the games's gone and that we use the right tactics."
New Zealand have added batsman Martin Guptill to fill out the test squad to the usual 13. Senior batsman Ross Taylor is making good progress from his quad injury and expected to train fully under lights tonight.
