Speaking to 1 NEWS today though, Heath Mills, head of the New Zealand Cricket Players Association, says that any proposed changes to the game would need to have evidence behind them, rather than just citing general player welfare.
"Most importantly, that we preserve the global game so that the best players were playing at all times".
"Player safety is obviously an aspect of it but, having seen what happened in Canberra a couple of weeks ago, I'm sure the match officials will put us in the best position and we won't have to worry about it too much".
The proposal to abandon five-days Tests in favour of four-day games featuring 98 overs per day will be considered by the ICC's cricket committee this year, with the European Central Bank supportive of the concept.
Tim Paine doesn't like the thought of four-day Tests but he's mindful of the fact players don't always get it right. Arguably Lyon's greatest Test match, a 12-wicket haul against Virat Kohli's India in Adelaide, featured a seven-wicket masterclass on day five; the day where slow bowlers have the chance to dominate on wearing pitches. Then you look at Cape Town in 2014 as well, that Test match where Ryan Harris bowled Morne Morkel with two overs to go; that's gone down to the last 10 minutes on a day five.
The Black Caps have already lost pacemen Trent Boult and Lockie Ferguson to injury on this tour and they can ill-afford any weakening of their batting in the face of Australia's fearsome bowling attack.
During the fourth day of the smoke-affected NSW v QLD Sheffield Shield game at the SCG, the AQI was 170.
One of their most famous victories in recent memory, the series-clincher against Pakistan in Abu Dhabi 13 months ago, also went well into day five. One, there's the weather element.
The ICC is considering introduction of four-day Tests as part of the World Test Championships from 2023, an idea which was supported by Cricket Australia CEO Kevin Roberts. I think it's worth giving a trial.
Australian paceman Peter Siddle has announced his retirement from worldwide cricket after a career spanning 11 years. Five-day Test matches, they are hard work especially if the conditions aren't in your favour.
"I'm a firm believer in five-day tests".
However, while the ICC suggest that the move would be centred around player workload management, cricketing cynics would argue that the change would accommodate more shorter form, domestic Twenty-20 leagues around the world.
Cricket Australia sent around reminders to staff about working with smoke, with strict protocols put in place to pull players off the field and suspend the action in the Sydney Test - much like during a rain delay if air quality levels reach a certain threshold deemed unsafe by the International Cricket Council.
