Catherine Wilkin is particularly appealing as a hard-case Kiwi battler with forthright views on child-raising and personal responsibility.
Her male counterpart is convincingly brought to life in Peter Hayden's warm portrait of a salt-of-the earth Kiwi bloke. Perhaps the play's finest creation is an instantly recognisable version of the over-indulged, couch-hugging teenager played with wonderfully gormless charm by Leighton Stichbury.
Theresa Healey wins considerable sympathy as a long-suffering wife while Brooke Williams' finely judged performance generates plenty of humour as an astoundingly incompetent legal counsel.
Playwright Arthur Meek has a great feel for the Kiwi vernacular and the dialogue is bubbling with wit and charm.
As secrets are revealed there are plenty of sharply dramatic jolts but also some unevenness in style with a flippant treatment of teenage suicide contrasting with the earnest tone of the 'sisters are doing it for themselves' resolution.
Simon Bennett's assured direction maintains a cracking pace while Tracey Collins' superb set captures the claustrophobia of a crowded farm house with the gnarled trunk of a remarkably well-constructed apricot tree representing the tenacity of rural communities.
