The "New Zealand 1990" contest was held in August 1990 over a period
of 5 hours.  Teams were of up to 4.

I don't have the official results for either division.  Three of the four
members of the 1989/90 world champion team competed in an unofficial
team and solved 6(?) problems.  The two leading official teams both solved
four problems.

Note on problemx.  I'm pretty sure that there are only two possible solutions
to this problem:

  7  3  2  1  1  1  2  1  1  1

and

 11  2  1  1  1  1  1  1  1  1

The problem has been reworded so that only the first is acceptable
(the first is definitely the only solution where each value
printed is in the range 1 to 9 inclusive).
