TESTING/RENOVATION

We can change the bias on your old wide drawing set to that of a modern model...contact us for details
There is currently no legal requirement to have your set tested in NZ for domestic play if the last date stamp is 1982 or later, international use requires the current date stamp is no older than 10 years.

We have severe reservations about the prescribed test World Bowls mandated to be done on a table since 2002 as it has a critical flaw. Without Part B wobble test it can not read and validate the "on-green bias" of un-balanced or dual-sole sole models when using the Balanced-Sole WRB Test Bowl.  We brought this matter and sand wear issues to the attention of World Bowls continually some years ago, no action has ever been taken. WB continue to charge testing tables operaters $1000/yr to have the right to test bowls, manufacturers fee is in excess of $20,000 annually. We remain certificated bowls testers but sets requiring an official WB stamp will have to be sent to Australia as our table is un-registered, we regret any inconvenience caused.

Manadatory 10 year testing was stopped in NZ in 1983, however the test table is a very useful tool for checking set grouping and original  factory bias settings. We do all aspects of re-bias, re-polish etc and. we recommend to get your set checked regularly especially if all 4 bowls are not used often.

Testing over past 20 years shows approx 60% not legal for play under the Rules mainly due to playing on sand topped synthetic grass first introduced in the early 80's and although administrators knew of the significant wear factors, testing was stopped at this time. [ Bowls are to have a bias not less than the Working Reference Bowl and group on a table within 100mm/4" circle see other details below.] Many of the sets we see have quite noticeable bias changes, many going wider than when new and some with huge variation within the 4 bowls.

Below is a WB Test certificate indicating the criteria checked. In addition a set of bowls must be "a set of 4 bowls" of the same make, model, serial number, colour and emblem marking & painted colours.
