England need a further 210 runs to wrap up a series victory over New Zealand, having been set 258 to win after a brilliant century from former captain Kane Williamson.
Only three teams have ever lost a Test after enforcing the follow on, but England could join that list after New Zealand's much improved performance with the bat in their second innings.
Should England reach the target, it will be the second-highest successful run chase in Wellington behind Pakistan's 277 in 2003. But while it may be a challenging prospect for England, they did complete four even bigger run chases last summer including three against New Zealand.
