Rugby should get used to referees' increased use of the television match official, according to Blues coach Sir John Kirwan.
The game was too fast for referees and his assistants to be always convinced about incidents and they were often unsighted.
The Blues' latest clash with the Highlanders demonstrated those difficulties as Steve Walsh asked TMO Ben Skeen for verdicts about seven incidents including Ma'a Nonu's illegal tackle on Piri Weepu.
Kirwan denounced those who said the interruptions destroyed the rhythm and flow of the match.
