Auckland: Coach Stephen Kearney says NRL bosses are paying lip service to the "extreme sacrifice" the Warriors must make as the departure date for their Australian vigil nears.

An exasperated Kearney says he cannot fathom why the NRL has shut down communication lines with the Kiwi club for nearly a week since announcing a proposed May 28 restart date.

The Warriors are under the impression they will need to depart this Sunday if they're to participate in the rebooted competition, catering for two weeks in quarantine followed by a training period.

However, chief executive Cameron George has had no tangible response since firing a host of questions across the Tasman last Friday morning related to the Warriors' involvement.
