MetService last night wasn't quite forecasting a return to the golden climate, but it was expecting fine weather by the 2.35pm kick-off, after showers this morning. Significant westerly winds were also forecast for the region today.
Mr Campbell said that was something out of everyone's control, but what was in control was whether people got to the game on time. Last Sunday there were still an estimated 750 people "unticketed" at the gates when the Magpies kicked off into the wind, some missing the three tries during the next nine minutes.
The first of two schoolchildren's curtain raisers will start at 12.30pm, and Mr Campbell said: "Get there early."
If the five-figures crowd numbers are achieved, crowd attendances for the three weekends of the All Blacks test and the two shield defences will have surpassed 44,000, figures unmatched since the 1960s.
Today's crowd will include at least 200 who've bought tickets made available specifically for supporters of Bay of Plenty, a union which 92 years ago almost stopped Hawke's Bay's 1922-27 Ranfurly Shield tenure from ever happening, missing a kick from in front on fulltime as Hawke's Bay won 17-16 in its first-ever defence of the trophy, at Nelson Park in Hastings.
Bay of Plenty had to wait 82 years before finally winning the shield in 2004, but had just one successful defence.
A big crowd is also expected at the racecourse in Hastings where the nine-race second day of Hawke's Bay Racing's Spring Carnival starts at 12.25pm, and features the the $200,000 Windsor Park Plate, timed to start at 4.33pm, about 15 minutes after the rugby ends just 11km away.
The big events, coupled with the observance of some of the traditions of Election Day, sparked warnings from police about drink-driving and other safety on the roads.
Eastern District road policing manager Acting Inspector Matt Broderick said as it was with any events which involved the sale and consumption of alcohol police would be focusing on people driving from the shield match and the races.
"They will both be centres of attention for us as we do not tolerate alcohol and driving - we will be targeting that risk appropriately," Mr Broderick said.
Checkpoints and routine patrols would be used, although one other senior officer conceded there weren't any aimed at intercepting the shield should it somehow be headed up State Highway 5 towards Rotorua and Tauranga after the big game.
