The two-day mixed doubles championships will be a dress rehearsal for the Naseby International Curling Rink, which will host the annual Pacific championships next month.
Sean (33) and Bridget (28) Becker finished eighth at the world mixed doubles championships in Finland from 26 teams this year.
If the Beckers win again, they will represent New Zealand at the world championships in Italy in March.
The Beckers are two of the most experienced international curlers in New Zealand and have been named in the New Zealand team for the Pacific championships in Naseby.
Sean, a Maniototo farmer, will be playing in his 13th Pacific championships and his 11th as the New Zealand skip.
Bridget, a teaching administrator in Melbourne, will be returning home to the family farm for the event.
She is skip of the women's team for the Pacific championships.
The main opposition to the Beckers this weekend will come from teams that are also filled with New Zealand representatives.
Scott Becker, a bar manager from Christchurch, and Dunedin personal trainer Brydie Donald will challenge the Becker siblings.
Scott Becker (23), the younger brother of the siblings, will be contesting the Pacific championships for the second time.
This will be Donald's eighth year in the New Zealand team.
The Ranfurly pair of Warren Kearney and Marisa Jones have the local knowledge and experience in the international arena.
Kearney, the junior development officer for the Otago Rugby Football Union, will be making his second appearance at the Pacific championships and Jones has been an international for the last six years.
Another Maniototo pair keen to challenge the Becker sibling combination are Warren Dobson, who will be playing in his seventh Pacific championships, and Cass Becker in her first.
Cass Becker is the wife of Sean Becker.
A Hamilton combination that should not be underestimated is the husband and wife team of Lorne and Carol DePape.
Lorne DePape was a member of the New Zealand team at the Winter Olympics in Turin in 2006.
The mixed doubles will give the New Zealand team a useful workout before the Pacific championships to be held from November 1-9 in Naseby.
Two years ago, New Zealand experimented with the Canadian policy of selecting the winning team at the national championships for the Pacific championships.
But it did not work and New Zealand lost its momentum and is now out of the running for the Winter Olympics in Vancouver in 2010.
New Zealand, unlike Canada, has only a small base of players capable of playing in the international arena and must select the best to have any chance of getting back into the Olympics in 2014.
"We have a new-found confidence this year," Sean Becker said.
"We developed a good understanding at last year's championships and now know what our strengths are."
China won the Pacific championships for the first time last year and finished fourth at the world championships.
Australia was second and also qualified for the world championships.
The other teams competing in Naseby next month are Japan, Korea and Taiwan.
Fifteen teams are contesting the New Zealand mixed doubles this weekend.
The final will start at 3pm tomorrow.
