How embarrassing that we have such dismal sunshine despite a complete lack of rain for more than a month. It feels like Lima here.
I was surprised at Chch's low total. Normal for Southland and Otago but not expected for Canterbury. At least Jan. and Feb. were sunnier than usual. I see what you mean re cloudy weekends!

You had your 2nd sunniest summer. January's value was a record high for you. The cloudiness this month is certainly not confined to your city. Even NZ's sunniest climes have had embarrassingly cloudy months at times, and Blenheim's 139 hours in Feb. of last year was about 90 below average (and it wasn't a wet month, either). In a "2100+" climate there is no guaranteed insurance against odd dull month which is also dry.
It's Wellington's turn at the moment to do better - we suffered through a 2.5 year period (start 2010 to August 2012) with a very large accumulated sunshine deficit around the 400 hour mark, much higher than that for Ch'ch over the same period. Fortunately September onwards has seen a substantial cumulative surplus, in fact Sept-Feb total is 2nd only to 2005-6.

Record low March totals for NZ include several Canterbury locations, with Timaru's absymal 59 hours in 1979 at the bottom of the list.

Does the converse ever occur (i.e. wetter but sunnier than normal month)?

It certainly does. I doubt if there's a single station in NZ that can't cite good examples. The sunshine correlation with rain days rather than rainfall total might be slightly better, but still not that high.
Locally the most extreme example was December 1939 (also applied to Nelson and Marlborough and adjoining regions to some extent) - average sunshine, but two massive rainfall events produced 386mm of rain, about 400% of average and the highest ever recorded in a month here.
A quick calculation for Ch'ch Aero 1977-2011 shows annual rainfall correlation with annual sunshine gave a coefficient of -0.37, so not spectacular. I think the monthly (anti)correlation would be larger but not massively so.

Edit: correlations rainfall-sun for individual months were reasonable, but not all that consistent. Mostly in the -0.35 to -0.55 range, but March was -0.72 (high) but February almost zero! Rain days vs. sunshine gave slightly more consistent results but otherwise similar.
Nice cool change today, finally has come up to the Hunter after hitting Sydney in the early hours of the morning.
As with most cool changes in the March, it won't last long though, back to low 30's by late in the week, and even mid 30s next Saturday - hopefully that will be the grand finale to the warmth.
