Previous national champions Ali Forsyth and Tony Grantham, who missed selection in the recently completed Asia-Pacific championships where the Kiwi men's team were the best performed of the 18 countries, will both be looking for a good showing to attract the attention of the New Zealand selectors.
Current national Blackjack players and previous national champions Mike Nagy, Shannon Mcllroy, Andrew Kelly, Blake Signal and Paul Girdler are also in the field.
Young Taranaki player Cameron Nairne, who had a stellar season in 2014-15, is considered the best unheralded prospect.
The women's singles, featuring 120 players in 30 sections, and men's pairs will start tomorrow.
The women's field is also one of the best assembled in years with current internationals Jo Edwards and Val Smith expecting strong challenges from current Australian representatives Kelsey Cottrell and Sarah Boddington.
Also competing will be last year's winner Leigh Griffin of Wellington who will defend her title after a great performance in the recent World Champion of Champions singles.
The younger brigade will also keep their rivals sweating as they press for national selection with Mandy and Angela Boyd, Katelin Inch, Tayla Bruce and Amy McIlroy strong prospects.
