But it was Smith who was the star as the tournament started on Wednesday.
He picked up three wins and was the only undefeated player on the first day.
Smith accounted for Auckland's Bob Beetson 22-14, Otago's Murray Goldfinch 26-19 and McLay 21-16.
The competitors play three games per day, each lasting two and half hours.
The winner will be known after the last game on Sunday, finishing at 11am.
McNae said the tournament champion is decided by the most wins and if there is a tie then a countback is used from the number of overall points scored minus points conceded.
"Every point counts because they need it for net points."
The 14 players come from around the country, including Nelson, Gisborne and Wairarapa.
There is also a bit of an international connection.
Brigitte and Peter Westaway are representing Otago but are actually Canadian, splitting their time between the two countries.
Richard Williamson lives and plays his croquet in Auckland but is from the United Kingdom.
