The Operations Research Society of New Zealand is a nationwide not-for-profit body comprising academics and public servants, consultants and people in industry. It currently has over 150 members within New Zealand and is affiliated to APORS, IFORS and the Royal Society of NZ. In 2008, David Ryan was presented with an IFORS certificate (larger image) celebrating 50 years of IFORS.

The primary aim of the Society is to promote Operations Research and Management Science in New Zealand in both academic and industrial aspects.

The 2001 conference paper guidelines are available for download in Word format. (The 2000 conference paper guidelines are also available for download.) A sample LaTeX file from 1998 is also available.

The ORSNZ conference rotates around the NZ universities in the sequence Auckland (2002), Hamilton (2003), Wellington (2004) and Christchurch (2005). (Council resolution July 2001). This sequence was broken in 2004 for a joint conference, and to allow our 2005 40th year celebration to occur in our birthplace, Wellington (home of the old DSIR). The 2007 conference was not held in Hamilton at their request, but instead in Auckland.

Each visiting lecturer will be invited to write a guest editorial for the society newsletter. The ORSNZ contributes to the costs up to a maximum of $1000 plus GST (if any) per visitor. Each candidate must be nominated by a current member of ORSNZ, "the champion". The nomination must include the CV of the nominated visiting lecturer, the date and location of the hosts of the visit, the name of the champion and an undertaking by the champion to coordinate a visit by the nominee to three or more of the above named centres. Enquiries concerning, or nominations for, lectureships should be sent to president@orsnz... The closing date for nominations is the end of April. Information on past visitors can be found here.

View our 2009 constitution (dated 10 March 2009) (.doc) with changes (.doc) introduced by the amendment of 20 April 2009 (.doc) and discussed in the January 2009 newsletter. This version supercedes our 2008 consitution. We also have available the Aug 1990 Amendment (introducing honorary life memberships), Jan 1991 Constitution (ConJan91.doc), Dec 1991 Amendment (not-for-profit changes, collective members rights, sexist language), Feb 1992 Constitution (ConFeb92.doc), April 1993 amendment (ConVote1.doc) (financial year ending June, conduct of members), April 1993 Constitution (as filed) (ConJun93.doc) the Dec 2000 amendment (.doc) and voting result (Mar 2001 newsletter, p19), the Feb 2001 consitution (.doc) (which was never filed with the Companies Office), and the Jan 2008 constitution (.doc) (being the delayed filing of the 2001 version). Most of these Word files are the old originals!

Registration as an Incorporated Society
The ORSNZ is an incorporated society, number 216850, at the NZ Companies office. The 2009 constitution changed our name from the Operational Research Society of NZ to the Operations Research Society of NZ. This is shown in our updated Certificate of Incorporation from the Companies Office (which replaces our earlier 2007 Certificate of Incorporation). We were first incorporated on 24 May 1965.

We file annual accounts each year. There is some useful information for registered societies at http://www.societies.govt.nz/, including some useful forms and options for uploading reports and updating information.

Not GST Registered
On 10 June 2010, we deregistered for GST. (We were previously registered for GST under GST number 55-449-481.)

Registration as a Charity and IRD Donee Organisation Status
In May 1992, we were approved by IRD (confirmation letter, 25 Feb 2008) as a non-profit organisation for the purposes of income tax.

In April 2009, we were registered as a Charity by the Charities Commission, with registration number CC40246; view the Charities Commission Registration certificate. (This supercedes and extends our non-profit status.) IRD (IRD letter, 25 May 2009) have confirmed that tax credits and deductions can be claimed for donations to the ORSNZ.

Registration with the Charities Commission means we need to:
• send an Annual Return to the Commission each year. Our first Annual Return is due before 31 December 2009.
• notify the Commission of changes to the name, address for service, balance date, rules, purposes or officers no later than three months after the effective date of the change.

The ORSNZ was founded in 1965 by staff at the Applied Maths Division of the DSIR (Department of Scientific and Industrial Research), a government department based primarily in Wellington.We have a small collection of historic photos which were collected as part of our 2005 40th anniversary in Wellington, including:
1/ George Dantzig (Stanford Optimisation Lab) cutting our 21st anniversary cake, Aug-1985, with Bruce Benseman (President?), [jpg] and
2/ Jerry Brown (Naval Post-Grad College, Monterey), invited conference speaker, Aug-1987, again with Bruce Benseman. [jpg]

The comments for the following pictures were provided by Vicky Mabin (Jan 2008). These pictures featured in a picture quizz held in 2005 at the 40th anniversary of the ORSNZ.
1  APORS delegates, ORSA/TIMS Conference, Gold Coast: Tony Vignaux, Hugh Barr, Vicky Mabin.
2. 1999 Waikato conference:  Hans Daellenbach and Michael Rothkopf - Keynote Speakers. Hans did a brilliant futuristic piece for his address, the conference theme was OR in the new millennium.
3.  Canterbury Conference, 1992?
4.  No details of this were given by Vicky Mabin. However, this photo was shown at the 2012 Conference in Wellington as part of a presentation of the Hans Daellenbach prize to E. Grant Read. Discussion confirmed this was at Canterbury, and was probably in 1992. This conference was coordinated with a skiing trip (which explains David Ryan's tan! David is in front of Hugh Barr; Hugh is located rightmost in the back row.). The front row is ?, ? John Paynter, ORSNZ secretary, Grant Read (president at the time?), Hans Daellenbach, Les Foulds, ?, ?,  ?
5.  2001, Canterbury OR Dept 30th Anniversary Re-union including John George (and wife), Hans Daellenbach, Anne Spence/Wein and Larry Wein, Vicky Mabin, John Raffensperger, Ed Silver?, John Giffin, Victoria Coad, Nick Winter?, Jenny George, Don McNickle.
6. Bruce Benseman and George Dantzig, August 1985, ORSNZ 21st birthday celebrations, organised partly by Vicky Mabin (especially the cake!)  Don't be misled by the fact that we had our 40th in 2005 - we missed a conference in 1997 due to APORS in Melbourne that year.
7. Joint conference with NZPICS in Wellington, 1991, organised by Vicky Mabin (President of ORSNZ, Chair of Wgtn Chapter of NZPICS, and Conference Chair).
8. Waikato?   The speaker with Les looks like Saul Gass?

(Thanks to Bruce and John Hayes, Vicky Mabin, Karen Garner, and others I'm sure, for contributing these pictures.)

Lester Brian reports "The logo was selected from a competition by art students (from where? – perhaps Wellington?).  I remember laying the entries out over the floor at more than one meeting." (Email 26/11/2007) Our oldest newsletter (Feb 1970) includes in its AGM report: "Letterhead. The particular O.R. symbol was chosen as the arrows reflect a tension, and a choice between alternatives. It was agreed that we should express our appreciation for the quality of the work."
