If the home side were guilty of one thing, it was not playing to the conditions. Several times Rotorua would break out of their danger zone but instead of kicking low and behind Christchurch's defensive line they would look to spin it wide, only to cough up possession and have the visitors camped back on their goal line again.
The weight of possession soon told on Rotorua and they succumbed to the pressure when lock Nathan Evans broke through the defence to score. The conversion was unsuccessful and both sides went into the break cold, miserable and only a 5-0 buffer to Christchurch.
After the break the conditions got worse with the wind driving the rain sideways. However, it didn't dissuade Rotorua from continuing with their high-risk rugby.
The plan appeared to be to try and get the ball out to Jone Lasaganibau but Christchurch were well aware of his attacking capabilities and came up flat on the the big centre, not giving him any room to work.
Rotorua prop Jesse Williams was a solid workhorse at the breakdown. He was joined by No8 Renton Barrett who grafted in the ruck.
However, despite all their efforts Rotorua could not get the ball across Christchurch's line and had to settle for penalties from Savage. Poor discipline almost cost Rotorua the match, leading 6-5 and time almost up on the clock. The home side were penalised for being offside at the ruck. With the kick directly in front and 10m out, it was a gift, first-five Rose was happy to accept and converted to put Christchurch ahead. It was a quick sprint back to halfway for the Rotorua side who kicked the ball deep into the Christchurch 22. The Rotorua forwards, lead by captain Axle Hohneck, charged through the visitors like a herd of angry rhinos and won turnover ball.
For the first time in the second half Rotorua had good attacking ball inside the visitors' danger zone and they pressed hard. The pressure was too much and Christchurch, too urgent to push up and cut down Rotorua's attacking chances, were penalised for being offside.
With the ball only 5m in front of the posts Savage made easy work of the kick to the joy of his team-mates.
Rotorua's second match against Massey was a one-sided affair with Rotorua taking a 28-0 half-time lead and going on to win 50-0 against the visiting side.
