"I'll accept the fitness levels may not be as good as they should be in some cases but as I watched the wheels fall off in the second half it was easy to see it was more to do with the travel on the day," Blake said.
His players had to get up at 5am to catch their 7am flight from Napier to Christchurch where they had a half-hour wait before their next flight to Dunedin for the noon kick-off.
"Everything was a whole big rush. All the Otago girls and coaches were telling our girls to come and play for Otago as they never have day trips like that," Blake said.
The Tuis scrum struggled for the first 15 minutes before gaining parity. Halfback Gemma Woods seldom had quality ball to distribute.
Burkin and captain and openside flanker Laurae Blake were the best of the Tuis forwards.
Experienced props Natalie Cotton and Sharlena Maui made the most of their game time, while former Black Fern Williams had some classy moments.
For a 15-minute period in the second half the Tuis were down to 13 players when No8 Te Aroha Hunt and winger Kirsty Grace-Thomas were in the sinbin.
Fullback Talon Robinson is likely to be out of action for a fortnight with a shoulder injury.
